high Tenable Cloud Security Plugin ID 442189
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior
to 0.8.0, a Stored Cross-Site Scripting (XSS) vulnerability exists in the Banner component due to an
improper sanitization order (specifically, DOMPurify is executed before the marked library). This
vulnerability allows a compromised or malicious administrator to plant a malicious payload in the global
banner. Crucially, this vector enables Privilege Escalation, as the malicious banner is rendered for all
users, including the Super Admin (Primary Admin). Consequently, the payload successfully bypasses the
existing security mechanism. An attacker can leverage this to steal the Super Admin's session token This
vulnerability is fixed in 0.8.0. (CVE-2026-45665)
Solution
Update the open-webui library and its related packages to version 0.8.0 or later.See Also
