Overview
open-webui is an Open WebUI
Affected versions of this package are vulnerable to Infinite loop through the chat-history message deletion helper process. An attacker can cause the server to hang and deny service to all users by creating a cyclic chat tree and deleting a message, resulting in an infinite loop that blocks the server's request loop. This is only exploitable if a user with the default role creates a chat with messages referencing each other as children and then deletes a message from that chat.
