CyberRota Analysis

AI-Generated

The Open WebUI platform versions 0.9.5 to 0.11.1 are vulnerable due to improper handling of HTTP redirects when the AIOHTTP_CLIENT_ALLOW_REDIRECTS option is enabled, allowing authenticated users to redirect fetch requests to excluded hosts or sensitive internal services. This could lead to unauthorized data exposure or manipulation through web search and ingestion tools. Organizations using affected versions should prioritize updating to version 0.11.1 to mitigate potential security risks.

Original NVD Description

Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.9.5 until 0.11.1, server-side web fetches did not reapply WEB_FETCH_FILTER_LIST or private-address controls to HTTP redirect destinations when AIOHTTP_CLIENT_ALLOW_REDIRECTS was enabled. An authenticated user could redirect the aiohttp and requests fetch paths to excluded hosts, loopback, private networks, or cloud metadata services and route resulting content into web search, URL ingestion, page-fetch tools, or chat image processing. This issue is fixed in version 0.11.1.
