Summary

The Discourse AI plugin introduces a vulnerability that could potentially expose HTML entities present in conversations when shared in posts. If a user visits a post featuring a onebox linked to a conversation, these HTML entities may inadvertently leak into the Discourse application. The issue has been mitigated in a recent commit, and users are strongly encouraged to update their installations. For those unable to update, it is recommended to modify the 'ai bot public sharing allowed groups' site setting to prevent such leakage.
