OpenClaw: Voice-call Plivo replay mutates in-process callback origin before replay rejection
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.
