Aliases CVE-2026-41402
Summary OpenClaw: Zalo webhook replay cache cross-target messageId scope bypass ## Summary Zalo webhook replay cache cross-target messageId scope bypass ## Current Maintainer Triage - Status: narrow - Normalized severity: low - Assessment: v2026.3.28 replay dedupe is still keyed too broadly, but the issue should stay scoped to authenticated sibling-target delivery paths rather than arbitrary unauthenticated attackers. ## 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) - `4d038bb242c11f39e45f6a4bde400e5fd42e4ebf` — 2026-03-31T19:33:57+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 @smaeljaish771 for reporting.
