Overview
open-webui is an Open WebUI
Affected versions of this package are vulnerable to Information Exposure via the GET /api/v1/tools/, GET /api/v1/tools/list, and GET /api/v1/tools/id/{id} endpoints. An attacker can access sensitive source code and potentially embedded secrets by making authenticated requests to these endpoints as a non-admin user with only read access to a shared tool. This is only exploitable if a tool is shared with a read grant to the attacker, to one of their groups, or to all users, and the attacker does not have write access or the workspace.tools permission.
