Aliases CVE-2026-26328
Summary OpenClaw iMessage group allowlist authorization inherited DM pairing-store identities ## Summary Under iMessage `groupPolicy=allowlist`, group authorization could be satisfied by sender identities coming from the DM pairing store, broadening DM trust into group contexts. ## Details Affected component: `src/imessage/monitor/monitor-provider.ts`. Vulnerable logic derived `effectiveGroupAllowFrom` using both the static group allowlist and DM pairing-store identities (`storeAllowFrom`). This allowed a sender approved via DM pairing to satisfy group authorization in groups even if the sender/chat was not explicitly present in `groupAllowFrom`. This weakens boundary separation between DM pairing and group allowlist authorization. ## Affected Packages / Versions - `openclaw` (npm): affected `<= 2026.2.13` - `clawdbot` (npm): affected `<= 2026.1.24-3` ## Fix Commit(s) - `openclaw/openclaw@872079d42fe105ece2900a1dd6ab321b92da2d59` - `openclaw/openclaw@90d1e9cd71419168b2faa54a759b124a3eacfae7` Thanks @vincentkoc for reporting.
