OpenClaw: Plivo V2 verified replay identity drifts on query-only variants
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.tsnow derives the V2 replay key withcreatePlivoV2ReplayKey(...), which hashesgetBaseUrlNoQuery(url)plus the nonce.extensions/voice-call/src/webhook-security.test.tscontains the regression testtreats query-only V2 variants as the same verified request.
