OpenClaw: Plivo V2 verified replay identity drifts on query-only variants
Packages
Details
As written in the advisory (Markdown source, shown as plain text).
## 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`.
