OpenClaw: Telnyx Webhook Replay Detection Bypass via Base64 Signature Re-encoding
## Summary Telnyx Webhook Replay Detection Bypass via Base64 Signature Re-encoding ## Current Maintainer Triage - Status: narrow - Normalized severity: low - Assessment: Shipped v2026.3.28 replay hashing treated equivalent Telnyx Base64/Base64URL signatures as distinct requests, but signature verification still held, so lower to low. ## Affected Packages / Versions - Package: `openclaw` (npm) - Latest published npm version: `2026.3.31` - Vulnerable version range: `<=2026.3.28` - Patched versions: `>= 2026.3.31` - First stable tag containing the fix: `v2026.3.31` ## Fix Commit(s) - `ad77666054651c1fd77b1dc60fd6a8db6600a29a` — 2026-03-30T20:01:43+01:00 ## Release Process Note - The fix is already present in released version `2026.3.31`. - This draft looks ready for final maintainer disposition or publication, not additional code-fix work. OpenClaw thanks @AntAISecurityLab for reporting.
