OpenClaw's voice-call Twilio webhook replay could bypass manager dedupe because normalized event IDs were randomized per parse
## Impact Twilio webhook replay events could bypass voice-call manager dedupe because normalized event IDs were randomized per parse. A replayed event could be treated as new and trigger duplicate or stale call-state transitions. ## Affected Packages / Versions - Package: `openclaw` (npm) - Vulnerable versions: `<= 2026.2.22-2` - Patched version (released): `>= 2026.2.23` ## Remediation The fix preserves provider event IDs through normalization, adds bounded replay dedupe in webhook security validation, and enforces per-call turn-token checks on call-state transitions. ## Fix Commit(s) - 1d28da55a5d0ff409e34999e0961157e9db0a2ab ## Release Process Note `patched_versions` is pre-set to the released version (`2026.2.23`) This advisory now reflects released fix version `2026.2.23`.2.23`. OpenClaw thanks @jiseoung for reporting.
