Technical details
This is an authorization bypass (broken access control) vulnerability in the select_conv, delete_conv, rename_conv, and on_set_public_conversation functions in control.py. The root cause is insufficient ownership validation—the functions accept conversation identifiers from users without verifying that the requesting user owns the conversation before performing operations. An attacker can exploit this over the network by supplying arbitrary conversation IDs to read sensitive chat histories, delete other users' conversations, or modify conversation metadata without authentication checks. No special preconditions are known to be required beyond basic network access to the application. Patches may be available in later versions.
