SCA: security update for open-webui (GHSA-p78m-89r6-pgf7)

medium Tenable Self-Hosted Container Security Plugin ID 447949

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.6.27 until
0.11.1, backend/open_webui/utils/tools.py captured a cookie jar from the enclosing connection loop instead
of binding it to each external tool callable. When multiple tool servers were attached and a session or
system OAuth connection was processed last, a request to a different server configured for bearer
authentication could include the calling user's Open WebUI session cookies, allowing that server's
operator to reuse the session and take over the account. This issue is fixed in version 0.11.1.
(CVE-2026-87015)

Solution

Update the open-webui library and its related packages to version 0.11.1 or later.
