CyberRota Analysis

AI-Generated

The Open WebUI platform prior to version 0.10.0 is vulnerable to path-based blocklist bypasses, allowing attackers to circumvent hostname policies through improperly matched URL strings. This could lead to unauthorized access or data exposure, particularly in environments where strict hostname validation is critical. Organizations using affected versions should prioritize upgrading to 0.10.0 to mitigate potential security risks.

Original NVD Description

Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. Prior to 0.10.0, WEB_FETCH_FILTER_LIST matching compared configured host entries against URL strings and non-label-boundary suffixes, allowing path-based blocklist bypasses such as !internal.example.com in a URL path and sibling-domain matches that did not reflect the intended hostname policy. This issue is fixed in version 0.10.0.
