fix(security): pin provider egress to validated public addresses - #76
fix(security): pin provider egress to validated public addresses#76seonghobae wants to merge 10 commits into
Conversation
ModelClient._validate_provider is the SSRF/egress guard: it resolves a
provider host and must reject any address that is not a public,
globally-routable target ("provider resolves to non-public address").
It only checked is_private/is_loopback/is_link_local/is_multicast/
is_reserved, but that flag set does not cover every non-public range.
RFC 6598 shared address space (100.64.0.0/10 — carrier-grade NAT, and
commonly used for cloud-internal services/proxies) reports False for all
five flags while ipaddress.is_global is also False, so a provider whose
host resolved into 100.64.0.0/10 (or its IPv4-mapped ::ffff:100.64.x form,
or the unspecified address on interpreter versions where is_private is
False for it) passed validation and became a reachable internal SSRF
target.
Fix: also reject `not ip_address.is_global`. The explicit flags are kept
because some non-public multicast addresses report is_global True and must
still be blocked, so the OR-combination is strictly wider than before with
no regression: every previously blocked address stays blocked, genuinely
public unicast addresses stay allowed, and the shared-address-space gap is
closed.
Regression tests (getaddrinfo stubbed for deterministic offline checks):
- a host resolving to 100.64.0.1 must be rejected (fails before this fix)
- a host resolving to 8.8.8.8 must still be accepted (guards over-blocking)

sqlalchemy-execute-raw-query |
cost_ledger.py:586/605/625 |
Safe — parameterized DB-API queries; only fixed module-constant column names (_USAGE_COLUMNS, catalog columns) are interpolated, all values pass as ?/placeholder params. Already # nosec B608-annotated. |
unverified-ssl-context |
orchestrator.py:233 |
By-design — ssl._create_unverified_context() is gated behind an explicit, documented verify_tls=False dev-only opt-out (default verifies against the system store). Already # nosec B323. |
dynamic-urllib-use-detected |
orchestrator.py:310 |
By-design — the URL is provider-validated before the call (the exact egress path this PR hardens). Already # nosec B310. |
This does not block merge: .github/workflows/sast-semgrep.yml documents that the Semgrep job "does not affect auto-merge" (merge gating is CodeQL-only; Semgrep uploads SARIF to the semgrep code-scanning category). The findings pre-date this PR and would fail on any current-head scan.
Governance follow-up (tracked separately, not scope-creeping this SSRF PR): a focused base pass adding # nosemgrep: <rule-id> suppressions (Semgrep doesn't honor bandit # nosec) with the justifications above, verified against the pinned p/default config, to green the repo's SAST gate.

…bypass `ModelClient._validate_provider` blocks a provider whose base_url host resolves to a loopback/private/link-local/reserved address, but `_open_provider` executed the request with urllib's default global opener, which follows 3xx redirects to any http(s) URL with no re-validation. A configured provider whose response is malicious or compromised could answer `302 Location: http://169.254.169.254/…` (cloud metadata) or `http://127.0.0.1:…/` and the orchestrator would follow it and read the internal body back into the completion — exactly the upstream→ internal pivot the egress guard exists to stop. All egress (chat, stream, embeddings) funnels through `_open_provider`, so the whole client was affected. Fix: build a private opener in `ModelClient.__init__` whose `_EgressGuardedRedirectHandler` re-applies the resolved-IP egress policy (plus a `not is_global` catch for CGNAT / IPv4-mapped forms) to every redirect target and rejects non-http(s) schemes before following; `_open_provider` now uses that opener (TLS trust carried by its HTTPSHandler context). `_validate_provider` is left untouched so it composes cleanly with the first-hop hardening in #76. Adds `tests/test_ssrf_redirect_guard.py`: a fully-offline loopback repro (a provider that 302s to a loopback metadata address is refused, not followed) plus unit coverage of the host assertion and the handler's scheme/blocked/public branches. Verified red→green (without the guarded opener the integration test fails as the loopback body is returned). Full suite 295 passed; interrogate 80% gate passes with the new code fully docstringed.

The required Semgrep (multi-language SAST) gate failed on five findings, blocking OpenCode approval on the SSRF-egress fix. All five are verified false positives that already carry `# nosec` justifications; each now also gets the matching scoped `# nosemgrep` so the gate reflects real risk: - cost_ledger.py x3 sqlalchemy-execute-raw-query (ERROR): parameterized DB-API queries -- the f-strings interpolate only the placeholder symbol (?/%s) and the fixed _USAGE_COLUMNS constant / fixed clause templates; every value is bound as a driver parameter, so no untrusted value reaches raw SQL. - orchestrator.py unverified-ssl-context (ERROR): secure by default (verify_tls=True -> ssl.create_default_context()); ssl._create_unverified_context() is only reached on the explicit, documented dev-only verify_tls=False opt-out. - orchestrator.py dynamic-urllib-use-detected (WARN): the urlopen target is _provider_url(agent) after provider egress/SSRF validation (loopback/private/ reserved blocked), not user-controlled. Comments only (no behavior change); the gate is not weakened -- only these exact rule+line pairs are suppressed, with justification.

…3.13)
atheris publishes different newest versions per CPython: the repo fuzz job
runs CPython 3.11 where the newest published wheel is 3.0.0, while the
central OpenCode coverage-evidence image runs a newer CPython (3.13+)
where only 3.1.0 is published. A single unconditional pin cannot satisfy
both --require-hashes installs of this one lock:
- pinning 3.0.0 fails the central coverage image build on 3.13+
("No matching distribution found for atheris==3.0.0" -> "Trusted
coverage tool image build failed before PR execution"), blocking
OpenCode approval for every PR against this base;
- pinning 3.1.0 fails the repo's own "Atheris coverage-guided" job on
3.11 ("No matching distribution found for atheris==3.1.0").
Split the pin with environment markers (atheris==3.0.0 for
python_version < 3.13, atheris==3.1.0 for >= 3.13) and regenerate the
hash lock with the recorded `uv pip compile ... --python-version 3.11
--universal` command, so both interpreters resolve a published, hashed
wheel. Verified: pip on 3.11 selects 3.0.0 (cp311 wheel), pip on 3.13+
selects 3.1.0.

Superseded by #96, which preserves this PR's exact DNS-pinned provider-egress implementation and regression suite while adding the interpreter-portable Atheris lock required for same-head central coverage evidence. #96 exact head |

Closing as superseded by #96. PR #96 carries the reviewed DNS-pinned provider transport, global-routability rejection including RFC 6598, original-host TLS/SNI/certificate verification, proxy and redirect isolation, deterministic cleanup/retry behavior, and the interpreter-partitioned Atheris lock required by central coverage evidence. Keeping #76 open would duplicate the same security ownership and confuse the ordered integration stack. No branch-protection or exact-head evidence is bypassed; #96 remains the merge gate. |

Summary
Close the provider-egress SSRF gaps, restore portable fuzz dependency locking, and keep the repository's security gates evidence-based.
1. Reject every non-public provider address
ModelClient._validate_providernow blocks any address for whichis_globalis false, while retaining explicit private, loopback, link-local, multicast, and reserved checks. This closes the RFC 6598 shared-address-space and related non-globally-routable gaps without weakening multicast protection.Regression coverage proves that unsafe addresses are rejected and globally routable addresses remain allowed.
2. Pin the actual HTTPS connection to the validated DNS answer
Validation alone was insufficient because a conventional URL opener resolved the hostname again when opening the socket. A DNS change between validation and connection could therefore redirect egress to a private address.
The current implementation:
tests/test_provider_address_pinning.pycovers public IPv4/IPv6 normalization, unsafe and empty DNS answers, stale-pin invalidation, no transport-time DNS re-resolution, redirect rejection, approved-IP fallback, all-address failure, response cleanup, direct-IP dialing, SNI preservation, and TLS setup failure cleanup.Plain HTTP remains available only for the repository's existing private loopback integration helpers; the public provider validation boundary rejects HTTP before egress.
3. Keep Semgrep findings narrowly justified
Existing verified false positives retain rule-scoped suppressions for parameter-bound database queries and the explicit development-only TLS verification opt-out. The provider transport no longer relies on the dynamic HTTPS
urlopenpath.4. Repair Atheris installation across interpreters
The fuzz extra and hash lock select:
atheris==3.0.0for Python below 3.13; andatheris==3.1.0for Python 3.13 and later.This preserves the repository's Python 3.11 fuzz job while allowing the central coverage-evidence image on newer Python to install a published, hash-locked wheel.
Exact-head validation

The central OpenCode coverage image is materialized from the base branch.
mainstill contains the old unconditional Atheris 3.0.0 lock, which is unavailable to the image's Python 3.13+ interpreter. Consequently, this PR's own central coverage-evidence review cannot become green until this base-lock repair reachesmain; merging this exact head repairs subsequent coverage-evidence runs. Independent approval and every branch-protection rule remain mandatory and are not bypassed.Documentation
CHANGELOG.mdrecords the non-public-address guard, validation-time connection pinning, SNI preservation, redirect rejection, and interpreter-specific Atheris compatibility.
