AI-Generated

The built-in knowledge search tool in Open WebUI versions 0.7.0 to 0.11.1 is vulnerable, allowing authenticated users to enumerate identifiers, names, and descriptions of inaccessible knowledge bases due to a metadata filter bypass in eleven vector backends. This could lead to unauthorized information disclosure, potentially exposing sensitive data structures. Organizations using affected versions should prioritize upgrading to version 0.11.1 to mitigate this risk.

Original NVD Description

Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.7.0 until 0.11.1, the built-in knowledge search tool passed the caller's readable knowledge identifiers through a metadata filter, but the search methods in eleven shipped vector backends ignored that filter. An authenticated user on an affected backend could enumerate the identifiers, names, and descriptions of inaccessible knowledge bases from the shared collection, although the associated document text remained in separate collections. This issue is fixed in version 0.11.1.
