SCA: security update for open-webui (GHSA-73cq-mcgh-379c)

medium Tenable Cloud Security Plugin ID 445673

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
 0.11.0, automation recurrence parsing in backend/open_webui/utils/automations.py anchored minutely and
 hourly rules at a fixed date of 2000-01-01 and then walked forward one interval at a time to find the next
 run. A single FREQ=MINUTELY rule enumerates roughly a quarter-century of occurrences synchronously on the
 event loop that also serves scheduler, HTTP, and WebSocket traffic, and the scheduler recomputes the next
 run for every claimed row on each poll. This causes availability impact for every other user of the
 instance. This issue is fixed in 0.11.0. (CVE-2026-70489)

Solution

Update the open-webui library and its related packages to version 0.11.0 or later.
