Name of the Vulnerable Software and Affected Versions
Open WebUI versions prior to 0.10.0
Description
Improper matching in the
WEB FETCH FILTER LIST allows for blocklist bypasses. The system compares configured host entries against URL strings and non-label-boundary suffixes, which enables path-based bypasses (for example, including !internal.example.com within a URL path) and sibling-domain matches that deviate from the intended hostname policy.Recommendations
Update to version 0.10.0.
