### 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.
