CyberRota Analysis
AI-GeneratedThe Open WebUI platform versions prior to 0.10.0 are vulnerable due to a regular expression flaw in the parsing of skill mentions, which can lead to quadratic backtracking and potentially block the asyncio event loop when processing certain authenticated chat messages. This vulnerability could impact the performance and availability of the application, making it crucial for users of affected versions to upgrade to 0.10.0 to mitigate the risk. Organizations using Open WebUI should prioritize this update to ensure system stability and prevent potential denial-of-service scenarios.

Original NVD Description
Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.9.2 before 0.10.0, the SKILL_MENTION_RE and strip_re regular expressions in backend/open_webui/utils/middleware.py parsed <$skillId|label> skill mentions with overlapping quantifiers, allowing an authenticated chat message containing <$ without a closing > to trigger quadratic backtracking and block the asyncio event loop. This issue is fixed in version 0.10.0.
