high Tenable Self-Hosted Container Security Plugin ID 447893

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.9.6 until
 0.11.1, SafePlaywrightURLLoader in backend/open_webui/retrieval/web/utils.py validated a user-controlled
 hostname in Python and then let the Playwright browser resolve it again in the sync and async request
 interceptors. An authenticated user controlling authoritative DNS could return a public address to
 validation and an internal address to the browser, exposing responses from internal services or cloud
 metadata through web search or URL ingestion. This issue is fixed in version 0.11.1. (CVE-2026-87996)

Solution

Update the open-webui library and its related packages to version 0.11.1 or later.
