Description
## Summary Voice-call Plivo replay mutates in-process callback origin before replay rejection ## Current Maintainer Triage - Status: narrow - Normalized severity: low - Assessment: v2026.3.28 can still mutate Plivo callback origin before replay rejection, but this needs a captured valid callback for a live call so medium is overstated. ## 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) - `efe9183f9d2fd5e01c8068fa01f4a07a58a63c0b` — 2026-03-31T19:50:35+09:00 ## 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. Thanks @zsxsoft for reporting.
