Summary

Source-level security audit fixes (Redis exposure, executor boundaries, runner sandboxes, auth/DoS paths, stored-XSS path), task-lifecycle polish (workspace cleanup, debug capture of submissions), and a dashboard UX/perf pass (bounded sequence previews, py2Dmol structure snapshots, resource review hidden from the submission form).

Security fixes (per audit)

  • Redis: redis-server --requirepass via REDIS_PASSWORD (auto-generated and persisted by restart.sh setup); gateway publishes loopback-only; SLURM Redis publishes 127.0.0.1:6380 only.
  • Executor-scoped Docker socket: base worker is socket-free; new docker-compose.docker.yml adds the socket for job_executor: docker. SLURM workers can no longer inherit host Docker access (compose concatenates volume lists across -f files).
  • Secure cookie chain: host-nginx example forwards X-Forwarded-Proto; gunicorn trusts forwarded headers only from the compose gateway; AUTH_COOKIE_SECURE=true force for HTTPS-only deployments.
  • Runners assumed hostile: Apptainer --containall --cleanenv; Docker read-only rootfs + tmpfs /tmp (HOME=/tmp), cap_drop=ALL, no-new-privileges, pids_limit, no network.
  • API keys: indexed sha256 digest + O(1) lookup (no more O(users × KDF) scan). Existing API keys become invalid — users re-issue from the profile page.
  • Rate limiting + CAPTCHA nonces: Redis fixed-window / SET NX EX shared across gunicorn workers, with documented in-memory fallback when Redis is down. Also fixed a real bug where endpoint exceptions were swallowed by the limiter's Redis guard.
  • Per-input-kind content validators (FASTA/A3M/PDB/mmCIF/JSON) with generous complexity caps.
  • PRIME: vendored model code + trust_remote_code=False, fail-closed with remediation, optional weights manifest. Operator action required: copy the two pinned snapshots' custom modules into docker/runners/prime/vendor/ before enabling PRIME (see vendor/README.md).
  • Artifacts: Content-Disposition: attachment default + sandbox CSP; main app CSP drops 'unsafe-inline' (py2Dmol verified not to need it).
  • _safe_join: symlink-aware (realpath) containment on top of the lexical check.

Lifecycle & UX

  • Terminal tasks delete their per-task input workspace; results/manifest/audit rows untouched.
  • Every finalized task captures debug/submission.json + uploaded files under their original names into the results dir (part of the manifest/ZIP) for reproducible debugging.
  • Dashboard: bounded 4 KiB sequence previews (perf fix); structure tasks render a lazy py2Dmol alpha-trace snapshot via the new owner/admin-only GET /compute/api/tasks/<md5>/input; create-task review no longer shows resolved resources.

Deployment notes

  • restart.sh setup appends REDIS_PASSWORD to the env file and rewrites the legacy password-less broker URIs automatically; no manual migration needed for stock env files.
  • SLURM mode no longer requires DOCKER_GID.
  • Test the Apptainer --containall change against the real runner matrix on a SLURM node before rollout.

Tests

  • CI-equivalent gate: 479 passed, 4 skipped, 1 failed. The failure (test_auth_update_me_requires_bearer_not_cookie) fails identically at HEAD — pre-existing, unrelated.
  • Both compose merges validated with real docker compose config (docker mode: socket present; SLURM mode: socket absent, loopback ports, password URLs).

- ESM image: pin scipy==1.12.0 (esm_if1 inverse-folding import chain) and
  extend the build-time smoke import to cover it
- Resolve sacct/scancel/docker executables via shutil.which() so
  cancellation/reconnect fail cleanly when the binaries are absent

- Regenerate UI typing contract (drop unused QtCore import)

Co-Authored-By: Claude <noreply@anthropic.com>
- Redis: requirepass via restart.sh-generated REDIS_PASSWORD; gateway and
  SLURM redis publish loopback-only
- Compose: executor-scoped docker.sock (new docker-compose.docker.yml);
  SLURM workers no longer inherit host Docker access
- Secure cookie: trusted X-Forwarded-Proto chain (gunicorn
  --forwarded-allow-ips) + AUTH_COOKIE_SECURE belt-and-braces
- Runners assumed hostile: apptainer --containall --cleanenv; docker
  read-only rootfs, cap_drop=ALL, no-new-privileges, pids_limit, no network

- py2Dmol loading/parsing helpers extracted from task-results.js into a

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

📝 Walkthrough

Walkthrough

The pull request hardens server deployment and execution, adds authenticated Redis and upload validation, protects artifacts and authentication flows, introduces structure previews, vendors PRIME model code, improves task cleanup and debugging, and expands regression coverage.

Changes

Server security and deployment

Layer / File(s) Summary
Deployment boundaries and service configuration
server/docker-compose*, server/run/restart.sh, server/README.md, server/.env.example, server/revocompute/app.py
Redis authentication, loopback publishing, trusted proxy ranges, executor-specific Docker socket access, secure cookies, and stricter CSP rules were added.
Authentication, Redis, and upload validation
server/revocompute/auth.py, server/revocompute/redis_util.py, server/revocompute/ratelimit.py, server/revocompute/input_validation.py, server/revocompute/routes.py
API keys now use indexed SHA-256 digests. CAPTCHA and rate limiting use Redis with in-memory fallback. FASTA, A3M, PDB, mmCIF, and JSON uploads receive content validation.

Execution and user-facing flows

Layer / File(s) Summary
Artifact protection and structure previews
server/revocompute/routes.py, server/revocompute/static/js/*, server/revocompute/templates/*, server/docker/nginx/default.conf.template
Artifacts default to downloads with sandbox CSP. Authenticated task-input serving and lazy PDB/mmCIF previews were added. Templates now use inert JSON data elements.
Executor isolation and task lifecycle
server/revocompute/job/runners/*, server/revocompute/task_runtime.py
Docker and Apptainer isolation was strengthened. Symlink-aware path checks, debug submission capture, workspace cleanup, and recovery failure handling were added.
Scientific runner loading and build checks
server/docker/runners/esm/*, server/docker/runners/prime/*
ESM image checks now include SciPy and inverse-folding imports. PRIME loads vendored model code with remote code execution disabled and can verify weight manifests.

Validation and maintenance

Layer / File(s) Summary
Hardening and integration validation
server/tests/*
Tests cover authentication, Redis behavior, upload validation, executor boundaries, runner loading, task lifecycle handling, artifact responses, structure previews, and browser contracts.

Merge Risk: 🔴 Critical · up to 5bdeb

This PR changes production startup and isolation defaults, request throttling, input validation, task recovery, and retained submission data. The current head can prevent the web service from starting or weaken proxy security, while also leaving concrete PRIME, denial-of-service, credential-leak, cross-user throttling, recovery, and runner-compatibility risks. Merge should be blocked until the deployment and runtime issues are fixed or explicitly accepted.

P1 Badge Keep comments outside the folded Gunicorn command

The >- scalar folds these comment lines into the same command string, producing gunicorn ... --preload # Trust ... --forwarded-allow-ips ... revocompute.app:app. When executed through the shell, # discards the bind options and application target, so the web service exits instead of starting Gunicorn. Move the explanation above command: or otherwise keep it out of the scalar.

P1 Badge Normalize scalar auto_map entries before iterating

Transformers config.json files conventionally store entries such as "AutoConfig": "configuration_prime.PrimeConfig" and "AutoModel": "modeling_prime.PrimeModel" as strings, while only tokenizer mappings may be arrays. For such a pinned PRIME snapshot, this loop iterates individual characters and immediately tries to import an empty module from the first character, so both PRIME modes fail before loading their models. Treat scalar mappings as one entry and reserve list iteration for mappings that are actually lists.

P2 Badge Validate every uploaded input rather than only the primary

For multi-file tasks such as RFdiffusion, PLACER, LASErMPNN, and PRIME DMS, base_record["file_path"] and filename refer only to saved_inputs[0]. Consequently auxiliary PDB/mmCIF/JSON/FASTA files bypass both the full-file NUL check and the new format/complexity validators, even though those files are included in TASK_INPUTS and parsed by runner code. Validate each item in saved_inputs before creating the task so malformed auxiliary inputs cannot reach third-party parsers.

P2 Badge Read the persisted Redis password before generating another

require_env_file calls this function before sourcing ENV_FILE, so a new shell invocation normally has no exported REDIS_PASSWORD even when the file already contains one. Every build, down, reload, up, or restart invocation therefore appends and selects a new password; commands such as reload or build do not restart Redis, leaving the persisted configuration out of sync with the running broker and causing subsequently recreated individual services to lose Redis access. Check the existing env-file assignment before generating a secret.

Filter alternate locations and extra models in the PDB parser.

The parser accepts every ATOM record with a CA atom name. Two common cases produce a wrong trace:

  • Alternate locations: a residue with altLoc A and B contributes two coordinates, so the trace doubles back on itself.
  • Multi-model files (MODEL/ENDMDL): all models are concatenated into one frame, so the trace jumps between models.

Keep only the first altLoc and stop at the first ENDMDL.

     var frame = { coords: [], chains: [], position_types: [], plddts: [], position_names: [], residue_numbers: [] };

Bound the growth of the global viewer registries.

Each renderAlphaTrace call adds a new viewerId entry to window.py2dmol_staticData and window.py2dmol_configs, and never removes it. The dashboard calls this once per opened structure card, so entries and their frame arrays accumulate for the lifetime of the page. On a dashboard with many structure tasks, this holds every parsed coordinate set in memory.

Consider deleting the previous entry when the container is re-rendered, or storing the data on the viewer element instead of on window.

29-47: 🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick win

Handle non-JSON error responses.

Line 29 always calls r.json(). A reverse proxy error page, a rate-limit response without a JSON body, or a CSP/WAF block returns non-JSON. The parse then rejects, and the outer catch shows "Network error. Please try again." even though the request reached the server. The user gets no indication that the reset was rejected or throttled.

Fall back to the status code when the body is not JSON.

370-380: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Close two gaps in the fail-fast validation block.

The block rejects an empty input_extensions and a non-positive max_input_files, but two adjacent cases pass:

  • primary_input_extensions: [] satisfies the subset check at Line 375, because the empty set is a subset of anything. The task type then loads with no primary input extension.
  • allow_multiple_inputs is not type-checked. A YAML value such as allow_multiple_inputs: "false" is a truthy string, so the guard at Line 379 is skipped and the flag reaches TaskType as a string.

Both are operator misconfigurations, so the cost of a wrong value is a confusing UI rather than a startup error. Validating them here keeps the failure at load time.

Align the failure handling of the two recovery branches.

The Docker branch now records a failure both when reconnect returns False (Lines 800-806) and when recovery raises (Line 809). The SLURM branch records a failure only for reconnect returning False; its except at Line 831 logs and moves on, so the task stays in running.

Pick one contract and document it. If "stay in running and retry on the next worker start" is the intended behavior for an unknown state, apply it to the Docker branch too. If terminal failure is intended, apply it to the SLURM branch.

Inline comments:
In `@server/docker-compose.yml`:
- Around line 125-128: Move the explanatory comments outside the folded command
scalar in the web service definition, keeping the command arguments—including
--forwarded-allow-ips, the bind address, and application target—on the
executable command line so they are not commented out by the shell.

In `@server/docker/runners/prime/Dockerfile`:
- Around line 26-29: The Docker build must provide the snapshot directories
required by run.sh instead of copying only vendor documentation and
placeholder.txt. Update the vendored model-code input used by the Dockerfile’s
COPY instruction to include the reviewed snapshot modules, or fetch an
immutable, verified source that supplies them before the copy occurs.

In `@server/docker/runners/prime/run.sh`:
- Around line 93-111: Normalize scalar auto_map values to one-item sequences
before iteration in both loader blocks: server/docker/runners/prime/run.sh lines
93-111 and 199-217. Apply this to AutoConfig and AutoModel entries so _load
receives complete entry strings rather than individual characters; preserve
existing handling for sequence values.

In `@server/revocompute/input_validation.py`:
- Around line 208-218: Update the JSON parsing flow before json.loads() and
_json_stats() so oversized inputs are rejected without allocating the complete
object graph; use a streaming parser or an appropriate pre-parse byte limit that
enforces the intended resource protection. Preserve the existing UTF-8, JSON
validity, node-count, and depth error behavior where applicable.

In `@server/revocompute/job/runners/slurm_runner.py`:
- Around line 71-82: Update server/revocompute/job/runners/slurm_runner.py lines
71-82 in SlurmJob.reconnect to return a tri-state result, distinguishing unknown
state from an inactive job when sacct is missing or exits non-zero. Update
server/revocompute/task_runtime.py lines 824-830 to keep the task running and
log when reconnect reports an unknown state, avoiding _record_failure and
workspace deletion; preserve failure handling for confirmed inactive jobs.

In `@server/revocompute/manage_db.py`:
- Around line 108-111: Replace ineffective skipcq: BAN-B608 annotations with #
noqa: S608 on the reported SQL f-string lines in server/revocompute/manage_db.py
at lines 127, 147, 179, and 263, and server/revocompute/resource_audit.py at
line 36. Remove any suppression requirement or annotation from the manage_db.py
line 111 SQL expression, since Ruff does not report S608 there.

In `@server/revocompute/ratelimit.py`:
- Around line 59-90: The distributed limiter currently keys on the gateway
address, so all clients share one quota. Configure the application to trust only
the known proxy hop, derive and preserve the sanitized canonical client address
at that boundary, and use it in the key built by the rate-limiting decorator
instead of request.remote_addr; add an integration test sending two client
addresses through the gateway to verify independent quotas.

In `@server/revocompute/redis_util.py`:
- Around line 39-40: Update the Redis exception handler in the Redis
connection/ping flow to avoid logging the authenticated REDIS_URL; log only a
redacted endpoint without credentials, or omit the URL entirely, while
preserving the existing warning and fallback behavior.

In `@server/revocompute/static/js/dashboard.js`:
- Around line 219-221: Update the structure snapshot markup in the task
rendering flow to derive the structure format from the primary uploaded filename
for lasermpnn, rfdiffusion, and placer tasks, distinguishing .pdb from
.cif/.mmcif inputs. Pass the derived format through data-format so
renderAlphaTrace selects the correct parser, while preserving the existing
fallback behavior for other cases.

In `@server/revocompute/task_runtime.py`:
- Around line 556-589: Update _capture_debug_submission so it does not copy full
input file contents into the retained debug/inputs directory; record only the
existing input metadata and hash in submission.json, or otherwise apply an
explicit bounded/failed-task-only policy that prevents large or sensitive inputs
from being retained. Preserve path validation and manifest generation for the
metadata that remains.

In `@server/tests/conftest.py`:
- Around line 166-170: Update the fixture’s REDIS_URL setup to call
get_redis.cache_clear() after every environment update, including when extra_env
supplies REDIS_URL; retain the existing default URL behavior and ensure
get_redis uses the current test configuration.

In `@server/tests/test_input_validation.py`:
- Around line 263-268: Update test_json_accepts_nesting_at_the_cap so the
generated document contains exactly MAX_JSON_DEPTH nested containers, while
preserving the assertion that validate_json accepts it.

In `@server/tests/test_security_hardening.py`:
- Around line 49-53: Update the test around generate_api_key to re-read the user
after key generation, then assert the persisted api_key_digest equals the
SHA-256 digest of the returned key instead of comparing against the stale user
record.

In `@server/tests/test_task_runtime_hardening.py`:
- Around line 63-72: Create the in-base symlink at base / "link", targeting base
/ "real", before the second _safe_join assertion in
test_safe_join_accepts_new_child_and_symlink_inside_base; keep the existing
assertion and expected lexical returned path unchanged.

In `@server/tests/test_tasks.py`:
- Around line 175-186: Update _insert_pending_task to accept caller-provided
content and use that value for input.pdb and its input snapshot; in the
structure-preview test, pass a minimal valid ATOM record so the endpoint
assertions exercise the PDB preview path instead of FASTA content.

In `@server/revocompute/static/js/py2dmol-preview.js`:

after the first ENDMDL and accept only the first alternate location for each
residue, ignoring subsequent altLoc records such as B. Preserve the existing CA
filtering and coordinate parsing for the selected records.
- Around line 126-135: Update renderAlphaTrace to remove or replace the existing
py2dmol_staticData and py2dmol_configs entries associated with a re-rendered

In `@server/revocompute/templates/task_results.html`:
- Around line 64-66: Remove the unused `#user-control-data` element from
server/revocompute/templates/task_results.html lines 64-66 and
server/revocompute/templates/user_control.html line 134; retain
`#result-task-data` because task-results.js consumes it, and do not alter
user-control.js behavior.

In `@server/tests/test_input_validation.py`:
- Around line 19-35: Replace bare conftest and revocompute imports with fully
qualified REvoDesign-rooted imports. Move reusable helpers such as
_load_pssm_module and _test_client_auth into an importable REvoDesign-rooted
support module, then update server/tests/test_input_validation.py lines 19-35
and server/tests/test_security_hardening.py lines 27-29 to use it and the
approved namespace for validation symbols.

YaoYinYing and others added 4 commits August 14, 2026 11:40
- docker-compose.yml: move the forwarded-allow-ips comment out of the
  folded gunicorn command scalar (comment text broke the command string
  and the web service failed to start — DockerFullStack CI failure);
  reword the REDIS_PASSWORD interpolation message (GitGuardian
  generic-password false positive)
- restart.sh: ensure_redis_password reads the password already persisted
  in the env file before generating a new one, so reload/build/down no
  longer desync from the running broker
- prime/run.sh: normalize config.json auto_map entries — scalars like
  "AutoModel": "modeling_prime.PrimeModel" were iterated character by
  character; both OGT and DMS branches fixed
- routes.py: content-validate every uploaded input of a multi-file task
  (primary and auxiliary), not just saved_inputs[0]
- tests: auxiliary-upload validation regression test

Co-Authored-By: Claude <noreply@anthropic.com>
- ratelimit: key the distributed limiter on X-Real-IP (the gateway nginx
  overwrites it with the socket peer), so each client gets its own quota
  instead of one shared gateway-address bucket
- redis_util: never log the authenticated REDIS_URL — redact credentials
  in the fallback warning
- input_validation: reject oversized JSON before json.loads allocates the
  full object graph (1 MiB pre-parse ceiling)
- slurm_runner.reconnect: tri-state (True/False/None); recovery leaves
  the task running when the job state is unknown instead of recording a
  failure and deleting the input workspace under a live job
- dashboard: pick the structure parser (pdb vs mmcif) from the uploaded
  filename, not from the task type's accepted extensions (types accepting
  both receive .pdb files too)
- tests: tri-state reconnect, JSON byte-ceiling regression tests

Co-Authored-By: Claude <noreply@anthropic.com>
- task_runtime debug capture hardlinks input snapshots into the results
  tree (copy fallback for cross-mount), so the workspace cleanup's disk
  savings are not undone by a duplicate copy
- tests/conftest: always clear the cached Redis client after REDIS_URL is
  set, including when a test overrides it explicitly

Co-Authored-By: Claude <noreply@anthropic.com>
- JSON depth: reject exactly at cap+1 (previously tested cap+2); accept
  stays at the cap
- API key: assert the stored digest equals sha256(key) after re-read
- _safe_join: actually create the in-base symlink before asserting it
- structure preview: seed a real PDB payload (helper gains a content
  parameter) so the input endpoint test exercises the PDB path
