Details

Kotaemon through 0.12.0 fails to properly validate conversation ownership in selectconv, deleteconv, renameconv, and onsetpublicconversation functions in control.py. Attackers can read other users' chat histories, delete conversations, or rename conversations by supplying arbitrary conversation identifiers without proper authorization checks.
