Problem

The official com.cmux.app TestFlight upload transferred successfully but Apple rejected the package with errors 90525 and 90166. The embedded CloudVPN.appex had no provisioning profile and an empty entitlement set, so App Store Connect never created a build record.

Fix

  • Resolve, validate, and install the App Store CloudVPN profile, creating it through App Store Connect when needed.
  • Map com.cmux.app.CloudVPN to that profile during manual App Store export.
  • Fail before upload unless the IPA contains a strictly signed CloudVPN extension with the packet-tunnel entitlement and matching embedded profile.
  • Keep CloudVPN profile handling opt-in so beta bundle lanes are unchanged.

Validation

  • bash -n passes for both changed shell scripts.
  • Targeted App Store lane tests pass for export signing, profile installation, profile fallback, and CloudVPN entitlement/profile checks.
  • ASC CloudVPN bundle ID and active profile were created and verified for the App Store lane.

Summary by cubic

Fixes App Store CloudVPN provisioning so the com.cmux.app TestFlight upload passes Apple validation instead of being rejected with errors 90525 and 90166.

  • Resolves, validates, and installs the App Store CloudVPN profile, creating it via App Store Connect when needed.
  • Maps com.cmux.app.CloudVPN to that profile during manual App Store export.
  • Fails before upload unless the IPA carries a strictly signed CloudVPN extension with the packet-tunnel entitlement and a matching embedded profile.
  • Keeps CloudVPN handling opt-in via IOS_APPSTORE_ENABLE_CLOUD_VPN so beta bundle lanes are unchanged.

Written for commit 6e67724. Summary will update on new commits.

Summary by CodeRabbit

  • New Features

    • App Store builds now support provisioning for the CloudVPN extension, including its network-tunnel permissions. Matching profiles can be supplied directly, reused when already installed, or retrieved through App Store Connect.
  • Bug Fixes

    • CloudVPN extension configuration is checked before upload. Builds with a missing extension profile or mismatched signing identity, application ID, or network-tunnel permission are rejected.

Walkthrough

The App Store workflows now enable CloudVPN provisioning-profile setup. The App Store lane maps the profile to the CloudVPN extension and verifies the extension’s signature, entitlements, and embedded profile before upload.

Changes

CloudVPN App Store support

Layer / File(s) Summary
Resolve and install the CloudVPN profile
.github/scripts/install-app-store-provisioning-profile.sh, .github/workflows/ios-app-store.yml, .github/workflows/ios-appstore-upload.yml, tests/test_ios_appstore_lane_identity.py
The installer accepts a supplied profile, reuses a matching installed profile, or resolves a profile through App Store Connect. It validates the CloudVPN application identifier and packet-tunnel entitlement. Both workflows enable CloudVPN profile setup. Tests cover the profile fixture, selection, and installation.
Map and verify the CloudVPN extension profile
ios/scripts/upload-testflight.sh, tests/test_ios_appstore_lane_identity.py
The App Store export maps the CloudVPN bundle identifier to its profile. The lane checks the exported extension’s signature, signed entitlements, and embedded profile. Test fixtures and assertions cover the export and validation flow.

Merge Risk: 🔵 Low · up to 6e677

The default App Store configuration is unaffected, but using a bundle-ID override or provisioning a second CloudVPN bundle under the same certificate can fail profile setup or export. Align the identifier and make profile names unique before relying on those configurations.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 6e677

The App Store lane gains stronger signing controls, but narrowing a shared check removes explicit CloudVPN identity validation from beta releases. Existing signing controls limit exposure. Production environment protections and recovery behavior remain partly unverified.

Retained concerns

  • Low · security · observed: The shared IPA verifier previously checked every embedded extension's signature, team, and application identifier. It now checks only NotificationService.appex, while the replacement CloudVPN verifier is App Store-only. Beta releases therefore lose explicit CloudVPN identity validation. Host signature and export controls remain; no unauthorized installation or platform bypass was demonstrated.
Security review details

Security Blast Radius

  • inferred — The immediate affected assets are release-runner provisioning state, the configured team's CloudVPN signing authorization, and uploaded iOS packages. The new remote mutation creates a profile for the selected bundle and certificate. The maximum authority of the existing App Store Connect credentials and runner isolation are not established by the supplied evidence.

Security Findings and Attack Paths

  • inferred — A beta export containing a CloudVPN signature with an unexpected team or application identifier no longer encounters the previous explicit extension-identity rejection. Exploiting this would require influence over build or signing inputs; no unprivileged source-to-publication attack or bypass of platform enforcement was demonstrated.

Trust Boundaries and Controls

  • observed — Provisioning inputs cross into release-signing state only after expected application-ID, packet-tunnel entitlement, distribution-profile and expiry checks. Certificate matching is conditional on resolving its fingerprint in fallback paths. The App Store publication boundary independently requires strict CloudVPN signature verification and matching signed/profile identities before upload.

Resilience and Maintainability Implications

  • inferred — Normal workflow serialization limits concurrent profile creation, and installed-profile reuse revalidates authorization before acceptance. Explicit validation failures stop publication. Interruption can leave remote or local profiles behind; concurrent invocation outside these workflows and cleanup on reused runners remain unverified.

.github/scripts/install-app-store-provisioning-profile.sh:18
🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Use the CloudVPN bundle-identifier override throughout the App Store lane.

install-app-store-provisioning-profile.sh accepts IOS_APPSTORE_CLOUD_VPN_BUNDLE_IDENTIFIER, but upload-testflight.sh always derives ${PRODUCT_BUNDLE_IDENTIFIER}.CloudVPN. A configured override can therefore install a profile for one identifier while the archive, export mapping, and IPA check use another identifier.

Suggested fix
-CLOUD_VPN_BUNDLE_IDENTIFIER="${PRODUCT_BUNDLE_IDENTIFIER}.CloudVPN"
+CLOUD_VPN_BUNDLE_IDENTIFIER="${IOS_APPSTORE_CLOUD_VPN_BUNDLE_IDENTIFIER:-${PRODUCT_BUNDLE_IDENTIFIER}.CloudVPN}"

Pass the resolved value to both archive commands:

       CMUX_HOST_BUNDLE_IDENTIFIER="$PRODUCT_BUNDLE_IDENTIFIER" \
+      CMUX_CLOUD_VPN_BUNDLE_IDENTIFIER="$CLOUD_VPN_BUNDLE_IDENTIFIER" \
       CMUX_NOTIFICATION_SERVICE_BUNDLE_IDENTIFIER="$NOTIFICATION_SERVICE_BUNDLE_IDENTIFIER" \

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Include the bundle identifier in the CloudVPN profile name.

When CloudVPN setup reaches ASC, json_active_profile_id_by_name selects the first active profile with the matching name. It does not compare bundle identifiers. A second configuration using the same certificate can therefore reuse the first profile. Validation then rejects its application identifier, and the script exits instead of creating the requested profile.

🐛 Suggested fix
-  profile_name="cmux App Store CloudVPN CI $profile_suffix"
+  profile_name="cmux App Store CloudVPN CI $CLOUD_VPN_BUNDLE_IDENTIFIER $profile_suffix"
