OpenClaw versions prior to 2026.2.25 contain an access control vulnerability in signal reaction notification handling that allows unauthorized senders to enqueue status events before authorization checks are applied. Attackers can exploit the reaction-only event path in event-handler.ts to queue signal reaction status lines for sessions without proper DM or group access validation.

- GHSA-792q-qw95-f446OpenClaw's Signal reaction-only status events could, in limited cases, be enqueued before access checks2026-03-03ghsa · osvUS
### Summary In a narrow Signal reaction-notification path, reaction-only inbound events could enqueue a status event before sender access checks were applied. ### Affected Packages / Versions - Package: `openclaw` (npm) - Affected: `<= 2026.2.24` (latest published at patch time) - Fixed: `2026.2.25` ### Details In the affected flow (`src/signal/monitor/event-handler.ts`), reaction-only handling could return after `enqueueSystemEvent(...)` before DM/group authorization checks were evaluated for that sender. This behavior was limited to reaction-only inbound events with reaction notifications enabled. In that case, a sender not authorized for normal DM flow could still queue a Signal reaction status line for that session. The fix applies shared DM/group access checks before reaction notification enqueue. Pairing behavior for normal DM messages is unchanged. ### Impact - Limited to Signal reaction-only inbound events. - Could add an unauthorized reaction status line to agent context for affected sessions. - Did not directly enable normal DM delivery or direct host command execution. ### Fix Commit(s) - `2aa7842adeedef423be7ce283a9144b9f1a0a669` ### Release Process Note `patched_versions` is pre-set to `2026.2.25` so once npm release is out, advisory publish can proceed directly. OpenClaw thanks @tdjackey for reporting.
