Name of the Vulnerable Software and Affected Versions Open WebUI versions prior to 0.6.19

Description Inconsistent authorization controls in the memories API allow a standard non-admin user to view, delete, and restore memories belonging to other users. A user can view existing memories using the 'POST /api/v1/memories/query' endpoint. Additionally, the 'POST /api/v1/memories/{memory id}/update' endpoint improperly leaks the content of a memory if a valid memory id is known, even if the user cannot modify the data. The 'DELETE /api/v1/memories/{memory id}' endpoint enables any user to delete memories, which can subsequently be restored by calling the 'POST /api/v1/memories/{memory id}/update' endpoint. This may lead to the disclosure of sensitive data and unique user ID values.

Recommendations Update to version 0.6.19.
