Summary

In Open WebUI prior to version 0.10.0, the WEB_FETCH_FILTER_LIST matching compared configured host entries against URL strings, allowing bypass of blocklists via path-based entries (e.g., !internal.example.com) and sibling-domain matches that did not reflect the intended hostname policy.

Risk Assessment

The risk involves bypassing access controls to internal resources, potentially leading to unauthorized data disclosure or SSRF attacks.

Recommendation

Upgrade Open WebUI to version 0.10.0 or later immediately to remediate the vulnerability.

Original NVD description (English source)

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.
