{"id":"CVE-2026-35618","aliases":["GHSA-cg6c-q2hx-69h7"],"url":"https://o3.security/vulnerability/CVE-2026-35618","summary":"OpenClaw < 2026.3.23 - Replay Identity Drift via Query-Only Variants in Plivo V2 Verification","details":"## Summary\nBefore `v2026.3.23`, the Plivo V2 verification path treated query-only variants of the same signed request as fresh verified work. Plivo V2 signatures authenticate `baseUrl + nonce`, but the replay key was derived from the full verification URL including the query string, so unsigned query-only changes minted a new `verifiedRequestKey`.\n\n## Affected Packages / Versions\n- Package: `openclaw` (npm)\n- Affected: `< 2026.3.23`\n- Fixed: `>= 2026.3.23`\n- Latest released tag checked: `v2026.3.23-2` (`630f1479c44f78484dfa21bb407cbe6f171dac87`)\n- Latest published npm version checked: `2026.3.23-2`\n\n## Root Cause\nThe vulnerable logic lived in `extensions/voice-call/src/webhook-security.ts`. V2 signature validation already canonicalized to the base URL without query parameters, but the replay key used the full `verificationUrl`, letting query-only variants bypass replay identity stability.\n\n## Fix Commit(s)\n- `b0ce53a79cf63834660270513e26d921899b4e5b` — `fix(voice-call): stabilize plivo v2 replay keys`\n\n## Release Status\nThe fix commit is contained in released tags `v2026.3.23` and `v2026.3.23-2`. The latest shipped tag and npm release both include the fix.\n\n## Code-Level Confirmation\n- `extensions/voice-call/src/webhook-security.ts` now derives the V2 replay key with `createPlivoV2ReplayKey(...)`, which hashes `getBaseUrlNoQuery(url)` plus the nonce.\n- `extensions/voice-call/src/webhook-security.test.ts` contains the regression test `treats query-only V2 variants as the same verified request`.\n\nThanks @smaeljaish771 for reporting.","published":"2026-04-09T21:26:51.509Z","modified":"2026-08-12T03:51:21.337805345Z","cvss":null,"epss":{"score":0.00283,"percentile":0.20255,"asOf":"2026-08-24"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.3.23"}],"fix":{"url":"https://github.com/openclaw/openclaw/commit/630f1479c44f78484dfa21bb407cbe6f171dac87","label":"openclaw/openclaw@630f147"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35618.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-cg6c-q2hx-69h7"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35618"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-replay-identity-drift-via-query-only-variants-in-plivo-v2-verification"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/630f1479c44f78484dfa21bb407cbe6f171dac87"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/b0ce53a79cf63834660270513e26d921899b4e5b"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:21.337805345Z"}}
