That mismatch allowed alternate encoded paths to evade protected-prefix auth checks while still resolving to `/api/channels/...` in plugin route handling.\n\nThe fix set hardens this class of issue by:\n- canonicalizing route paths to a bounded fixpoint,\n- failing closed on malformed or unresolved canonicalization depth,\n- requiring explicit plugin-route auth contracts (no implicit auth default),\n- enforcing route ownership/conflict guards for duplicate route registrations, and\n- using shared webhook route lifecycle registration to avoid stale/conflicting route surfaces.\n\n### Affected Deployments\nDeployments exposing plugin HTTP routes and relying on gateway auth for `/api/channels/*` protection.\n\n### Fix Commit(s)\n- `93b07240257919f770d1e263e1f22753937b80ea`\n- `2fd8264ab03bd178e62a5f0c50d1c8556c17f12d`\n- `d74bc257d8432f17e50b23ae713d7e0623a1fe0f`\n- `7a7eee920a176a0043398c6b37bf4cc6eb983eeb`","published":"2026-03-19T22:06:44.627Z","modified":"2026-08-12T03:51:28.154304290Z","cvss":null,"epss":{"score":0.00297,"percentile":0.22488,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.3.2"}],"fix":{"url":"https://github.com/openclaw/openclaw/commit/2fd8264ab03bd178e62a5f0c50d1c8556c17f12d","label":"openclaw/openclaw@2fd8264"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/32xxx/CVE-2026-32004.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-v865-p3gq-hw6m"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32004"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-authentication-bypass-via-encoded-path-in-api-channels-route"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/2fd8264ab03bd178e62a5f0c50d1c8556c17f12d"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/7a7eee920a176a0043398c6b37bf4cc6eb983eeb"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/93b07240257919f770d1e263e1f22753937b80ea"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/d74bc257d8432f17e50b23ae713d7e0623a1fe0f"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:28.154304290Z"}}
