Feishu Reaction Events Can Bypass Group Chat Security

GHSA-m69h-jm2f-2pv8
Summary

A security issue was found in Feishu's OpenClaw software. In some cases, a reaction to a group message could be treated as a private message instead of a group message, potentially allowing unauthorized users to post in the group. To fix this, update OpenClaw to version 2026.3.12 or later.

What to do
  • Update openclaw to version 2026.3.12.

Original title
OpenClaw: Feishu reaction events could bypass group authorization and mention gating
Original description
### 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.
