CVE-2026-41395
OpenClaw: Voice-call Plivo V3 webhook replay key uses unsorted URL, allowing replay via query-parameter reordering
Description
## Summary Plivo V3 signature verification canonicalized query ordering, but replay detection hashed the raw verification URL. Reordering query parameters preserved a valid signature while producing a fresh replay-cache key. ## Impact An attacker who captured one valid signed Plivo V3 webhook could replay the same event by permuting query parameters and trigger duplicate voice-call processing. ## Affected Component `extensions/voice-call/src/webhook-security.ts` ## Fixed Versions - Affected: `<= 2026.3.24` - Patched: `>= 2026.3.28` - Latest stable `2026.3.28` contains the fix. ## Fix Fixed by commit `85777e726c` (`Voice Call: canonicalize Plivo V3 replay key`).
