OCPBUGS-92747: CVE-2026-46597 — golang.org/x/crypto/ssh Denial of Service

Vulnerability

CVE-2026-46597 is a Denial of Service vulnerability in golang.org/x/crypto/ssh caused by crafted AES-GCM packet decoder inputs. An attacker could exploit malformed SSH packets to crash or hang the server.

Remediation steps

1. Replaced golang.org/x/crypto with a patched fork: Added a replace directive in go.mod to pin golang.org/x/crypto to github.com/openshift-sustaining/crypto v0.33.0-sec.4, which contains the fix for CVE-2026-46597.

2. Bumped transitive golang.org/x/ dependencies to compatible versions required by the patched crypto module:

   • golang.org/x/crypto: v0.14.0 -> v0.23.0 (replaced by patched fork)
   • golang.org/x/net: v0.17.0 -> v0.25.0
   • golang.org/x/sys: v0.13.0 -> v0.30.0
   • golang.org/x/text: v0.13.0 -> v0.22.0
   • golang.org/x/tools: v0.12.0 -> v0.21.1

3. Regenerated vendor directory: Ran go mod tidy && go mod vendor to sync all vendored dependencies with the updated go.mod.

4. Fixed test infrastructure to unblock CI after the dependency update:

   • test-backend.sh: Scoped the git status vendor consistency check to vendor/, go.mod, and go.sum only. The previous git status --porcelain --ignored was picking up unrelated ignored directories (e.g. node_modules/, .claude/), causing false positives.
   • build-i18n.sh: Resolved the i18next binary path absolutely using the script's directory. Yarn 4 does not inject node_modules/.bin into PATH for child shell processes, so the bare i18next command was not found.

5. Regenerated i18n locale files: Updated all frontend locale JSON files to reflect the current state of translation keys.

Test plan

• ./test.sh passes end-to-end (backend, frontend, demos)
• Backend: vendor consistency check, Go tests, gofmt, govet all pass
• Frontend: i18n check, yarn dedupe check, eslint, and 589 test suites (4063 tests) all pass
• Demos: dynamic-demo-plugin yarn.lock check passes
