GHSA-cg6c-q2hx-69h7: 
OpenClaw (formerly Moltbot or Clawdbot) vulnerability analysis and mitigation

Summary

Before 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.

Affected Packages / Versions

• Package: openclaw (npm)
• Affected: < 2026.3.23
• Fixed: >= 2026.3.23
• Latest released tag checked: v2026.3.23-2 (630f1479c44f78484dfa21bb407cbe6f171dac87)
• Latest published npm version checked: 2026.3.23-2

Root Cause

The 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.

Fix Commit(s)

• b0ce53a79cf63834660270513e26d921899b4e5b — fix(voice-call): stabilize plivo v2 replay keys

Release Status

The 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.

Code-Level Confirmation

• extensions/voice-call/src/webhook-security.ts now derives the V2 replay key with createPlivoV2ReplayKey(...), which hashes getBaseUrlNoQuery(url) plus the nonce.
• extensions/voice-call/src/webhook-security.test.ts contains the regression test treats query-only V2 variants as the same verified request. Thanks @smaeljaish771 for reporting.
