CyberRota Analysis
AI-GeneratedThe Open WebUI platform versions 0.8.8 to 0.11.0 are vulnerable due to improper access controls that allow authenticated users to access another user's knowledge attachments if they know the file ID. This flaw can lead to a read-only cross-user confidentiality breach, compromising sensitive information without affecting overall permissions or model validation. Organizations using affected versions should prioritize upgrading to version 0.11.0 to mitigate this risk.

Original NVD Description
Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.8.8 until 0.11.0, inline direct model metadata accepted client-supplied knowledge attachments without filtering them against the caller's read access. Any authenticated user who knew another user's file id could have the builtin knowledge tools return indexed chunks from that file, causing a read-only cross-user confidentiality loss while leaving knowledge-base permissions and saved workspace model validation unaffected. This issue is fixed in 0.11.0.
