GHSA-m69h-jm2f-2pv8

### Summary A Feishu reaction-originated synthetic event could misclassify a group conversation as `p2p` when the inbound reaction payload omitted `chat_type`. Authorization and mention-gating logic keyed off that incorrect chat type and evaluated the event as a direct message instead of a group message. ### Impact This could bypass `groupAllowFrom` and `requireMention` protections for reaction-derived events in Feishu group chats. ### Affected versions `openclaw` `<= 2026.3.11` ### Patch Fixed in `openclaw` `2026.3.12`. Reaction events now preserve the correct group context before authorization and mention-gate evaluation. Users should update to `2026.3.12` or later.
