CyberRota Analysis
AI-GeneratedOpen WebUI versions 0.9.0 to 0.11.0 are vulnerable due to inadequate validation of user-supplied URLs, allowing authenticated users to exploit the system by accessing internal or cloud-metadata IPv4 addresses through a NAT64 gateway. This could lead to unauthorized exposure of sensitive internal data via various content retrieval methods. Organizations using affected versions should prioritize upgrading to 0.11.0 to mitigate the risk of data leakage.

Original NVD Description
Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.9.0 until 0.11.0, Open WebUI checked whether a user-supplied URL destination was globally routable by applying ipaddress.is_global to the literal IPv6 address without examining IPv4 addresses embedded in transition encodings. On a deployment with a NAT64 gateway, any verified user could wrap an internal or cloud-metadata IPv4 address in the NAT64 well-known prefix, pass the filter, and receive the internal response body through RAG URL ingestion, URL-to-markdown conversion, or web-search content retrieval. This issue is fixed in 0.11.0.
