A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

Open WebUI from 0.11.0 before 0.11.4 contains an information disclosure vulnerability that allows authenticated non-admin users with tool export permission to obtain tool source code shared with them read-only. Attackers can request GET /api/v1/tools/export to retrieve the full Python source of read-only shared tools, exposing embedded API keys and credentials.
