{"id":"GHSA-cg6c-q2hx-69h7","summary":"OpenClaw: Plivo V2 verified replay identity drifts on query-only variants","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: `\u003c 2026.3.23`\n- Fixed: `\u003e= 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.","aliases":["CVE-2026-35618"],"modified":"2026-04-10T20:42:17.848062Z","published":"2026-03-26T18:56:32Z","database_specific":{"github_reviewed_at":"2026-03-26T18:56:32Z","nvd_published_at":null,"cwe_ids":["CWE-294"],"severity":"HIGH","github_reviewed":true},"references":[{"type":"WEB","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":"WEB","url":"https://github.com/openclaw/openclaw/commit/630f1479c44f78484dfa21bb407cbe6f171dac87"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/b0ce53a79cf63834660270513e26d921899b4e5b"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openclaw-replay-identity-drift-via-query-only-variants-in-plivo-v2-verification"}],"affected":[{"package":{"name":"openclaw","ecosystem":"npm","purl":"pkg:npm/openclaw"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2026.3.23"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-cg6c-q2hx-69h7/GHSA-cg6c-q2hx-69h7.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N"}]}
