CVE ID :CVE-2026-44564 Published : May 15, 2026, 8:16 p.m. | 1 hour, 8 minutes ago Description :Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.0, the ydoc:document:update Socket.IO event handler checks whether the sender is a member of the document's Socket.IO room (line 678) but does not verify that the sender has write permission. Users with read-only access join the document room via ydoc:document:join, which only requires read permission (line 520). Once in the room, the user can emit ydoc:document:update events that modify the in-memory Yjs document state and are broadcast to all other collaborators in real time. This vulnerability is fixed in 0.9.0. Severity: 5.4 | MEDIUM Visit the link for more details, such as CVSS details, affected products, timeline, and more...
