In a narrow Signal reaction-notification path, reaction-only inbound events could enqueue a status event before sender access checks were applied.
openclaw (npm)<= 2026.2.24 (latest published at patch time)2026.2.25 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.
2aa7842adeedef423be7ce283a9144b9f1a0a669patched_versions is pre-set to 2026.2.25 so once npm release is out, advisory publish can proceed directly.
OpenClaw thanks @tdjackey for reporting.
