CyberRota Analysis
AI-GeneratedThe Open WebUI platform versions 0.9.0 to 0.11.0 are vulnerable due to a flaw in the automation recurrence parsing, which can lead to significant performance degradation by overwhelming the event loop with excessive scheduling tasks. This results in availability issues for all users of the instance, as the scheduler struggles to manage concurrent HTTP and WebSocket traffic. Organizations using affected versions should prioritize upgrading to version 0.11.0 to mitigate this risk.

Original NVD Description
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.
