SCA: security update for open-webui (GHSA-v39v-59xw-j98g)

medium Tenable Cloud Security Plugin ID 447930

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 0.9.0 until
 0.11.1, backend/open_webui/models/calendar.py stored the calendar event meta.alert_minutes value without
 type validation and the shared upcoming-event scheduler compared that value numerically. An authenticated
 user with the calendar permission could store a non-numeric alert_minutes value that raised an exception
 and aborted the instance-wide alert pass, suppressing all users' reminders while the event remained in the
 lookahead window. This issue is fixed in version 0.11.1. (CVE-2026-87012)

Solution

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