EPSS · scored 2026-10-27

OpenClaw before 2026.3.31 contains a scope bypass vulnerability in webhook replay cache deduplication that allows authenticated attackers to replay messages across sibling targets using the same messageId. Attackers can exploit overly broad cache keying to bypass replay protection and deliver duplicate webhook messages to unintended targets.

    ## 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.
