Summary

Resolves all 15 open Dependabot alerts (6 high, 5 moderate, 4 low). Every one is a transitive npm dependency of Expo's build tooling in mobile/package-lock.json. None of these packages ship in the employee app bundle, and no gems or root package.json packages are affected.

The mobile CI gate (audit:security) currently fails on main with Unremediated advisory: GHSA-3g3m-2fjr-6pw4, because these advisories were published after the last mobile run on Oct 27. This PR makes it pass again.

  • node-forge 1.4.0 → 1.4.2 (lockfile only, inside Expo's ^1.4.0). This fixes 12 alerts. 1.4.2 also adds canonical DigestInfo re-encoding, the upstream fix for GHSA-86w9, which Dependabot still lists as "no fix" (Add community thread review with group discount codes #61). The local RSA backport is removed, and the existing forged-signature regression test now passes against unpatched 1.4.2.
  • glob 13.0.6 → 14.0.3, minimatch 10.2.6 → 11.0.3 via overrides. These are majors, the same pattern as the existing zod override. Expo SDK 58, including the latest 58.0.22, still declares glob ^13 / minimatch ^10, and neither line has a fix. The breaking changes were checked against every Expo call site (see below).
  • deepmerge 4.3.1: there is no upstream fix (4.3.1 is the latest release), so it gets a source-hashed backport under the existing security/backports.json mechanism. getKeys() no longer returns an own __proto__ key.

# Severity Package Advisory Fix in this PR

67 high node-forge GHSA-hqq3-7jhf-c5jx TLS stack exhaustion 1.4.2 (lockfile)

73 high node-forge GHSA-7wch-p9px-956x PEM ReDoS 1.4.2 (lockfile)
61 high node-forge GHSA-86w9-cpqp-85rv nested DigestAlgorithm (listed "no fix") 1.4.2 canonical DigestInfo check; local backport retired; Dependabot should auto-close (range <= 1.4.0)

76 low node-forge GHSA-4642-5mcj-2rqw OID arc truncation 1.4.2 (lockfile)
77 moderate glob GHSA-3g3m-2fjr-6pw4 abort bypass override → 14.0.3
78 moderate minimatch GHSA-g3hv-75wg-m249 globparts amplification override → 11.0.3
65 low deepmerge GHSA-gcqx-w48m-w2h4 __proto__ poisoning (no upstream fix) source backport; alert stays open: dismiss as "Vulnerable code not used / mitigated" (lockfile still says 4.3.1)

Reachability (all build-time only)

  • node-forge: @expo/cli (self-signed dev-server certificates) and @expo/code-signing-certificates (EAS Update signing, not used by Rupert).
  • glob: expo start/export/prebuild, config plugins, metro watch folders and fingerprinting. expo start does pass signal: AbortSignal.timeout(5000), but only over the project's own files.
  • minimatch: @expo/fingerprint ignore patterns, which come from Expo and the project.
  • deepmerge: @expo/config merges the project's own app config.

Major-bump compatibility check

  • minimatch 11 removes makeRe(), Minimatch#regexp, AST, matchOne() and the debug option. Nothing in @expo/* uses them. Fingerprint uses only new Minimatch(), .match(), .pattern and .negate.
  • glob 14 changes ignore patterns that start with / (none of Expo's do), returns arrays from the internal GlobWalker, and removes debug. Expo uses only glob() / globSync() with cwd, ignore, absolute, dot, nodir and signal.
  • New tests run Expo CLI's own TypeScript-file glob (with signal and ignore), an aborted walk, and fingerprint isIgnoredPath, including negation.
  • minimatch 11.0.4 was skipped: it was published under a day ago and drops Node 18.

Verification (local, Node 22.23.1)

  • node ../bin/check-mobile-sdk.mjs --self-test and the check itself: pass (Expo 58.0.17, 9 packages)
  • npm run verify:security, typecheck, npm test (15/15, including 3 new ones) and audit:security (0 unremediated): pass
  • expo-doctor@1.21.4 (with CI's EXPO_DOCTOR_SKIP_DEPENDENCY_VERSION_CHECK=1) and npm run export (iOS and Android, Hermes): pass (Doctor 19/19, both platforms exported)
  • Web/Rails is untouched (no Gemfile changes); PR CI runs that suite.

Known and pre-existing, not changed here: the online expo install --check (npm run check:dependencies) reports Expo patch drift (expo 58.0.22, react-native 0.88.1, expo-system-ui 58.0.7, and the lockfile's typescript 7.0.2 against ~6.0.3). That is identical on main and is the job of Dependabot #598/#599.

No migrations, web code or app source are touched.

- node-forge 1.4.0 -> 1.4.2 (lockfile only, within Expo's ^1.4.0): fixes
  12 advisories, including GHSA-86w9 via canonical DigestInfo checks, so
  the local RSA backport is retired.
- overrides: glob 14.0.3 (GHSA-3g3m) and minimatch 11.0.3 (GHSA-g3hv).
  Expo SDK 58 still declares glob ^13 / minimatch ^10, which have no fix.
  Breaking API changes checked against every Expo call site.
- deepmerge 4.3.1 has no upstream fix: source-hashed backport so getKeys()
  never returns an own __proto__ key (GHSA-gcqx).
- Regression tests for fixed versions, deepmerge poisoning, and Expo's
  glob/fingerprint matching under the new majors.

Restores the fail-closed audit:security gate, which fails on main since
the glob advisory was published. Build-time tooling only; nothing here
ships in the app bundle.

bundler-audit on main fails on advisories published today against
loofah 2.25.2, nokogiri 1.19.4 and rails-html-sanitizer 1.7.1.
Conservative update of only those three gems to loofah 2.25.3,
nokogiri 1.19.7 and rails-html-sanitizer 1.7.2.

The test read /proc/loadavg and /proc/meminfo directly, so it failed on
a Mac. HostVitals now reads /proc through one small method that the
test stubs with fixed contents, checking the exact CPU and memory
percentages instead of only their types. Disk and database size still
come from the real host. The real /proc read still runs where /proc
exists (Linux CI). A new test pins that an unreadable reading is nil.

Under a C/POSIX locale (a shell without LANG, as on some Macs) Ruby
returns ENV values as binary, so a label such as "SER8 · Incus" did
not equal the UTF-8 string and the platform overview test failed. The
label is now read as UTF-8, and a value that is not valid UTF-8 shows
as "Not configured" instead of raising.

PosPaymentReconciliationJob takes one machine-wide flock and skips its
sweep when the lock is held. Parallel test workers shared that file, so
when two PosCardPaymentTest cases ran the job at the same moment one
silently did nothing. That intermittently failed the overlap test
(line 72) and the rotation test (line 56) on main and on several PRs.

The lock path is now one small method, and the tests point it at a
temporary file per test. Holding the real lock from another process
reproduces both failures on the old code, and they pass on the new.
Production still uses tmp/locks/pos-payment-reconciliation.lock.
