Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.30%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
MOVO through 0.2.3 contains an authorization bypass vulnerability in the chat-api document endpoints that allows authenticated users to access other users' stored objects by supplying arbitrary object paths. Attackers who know a target's object path can send it to /api/documents/fetch or /api/documents/save-blueprint to read private documents and overwrite presentation blueprints.
