CVE-2026-33510 Details
Description
Homarr is an open-source dashboard. Prior to 1.57.0, a DOM-based Cross-Site Scripting (XSS) vulnerability has been discovered in Homarr's /auth/login page. The application improperly trusts a URL parameter (callbackUrl), which is passed to redirect and router.push. An attacker can craft a malicious link that, when opened by an authenticated user, performs a client-side redirect and executes arbitrary JavaScript in the context of their browser. This could lead to credential theft, internal network pivoting, and unauthorized actions performed on behalf of the victim. This vulnerability is fixed in 1.57.0.
A DOM-based Cross-Site Scripting (XSS) vulnerability has been identified in Homarr versions prior to 1.57.0, specifically on the '/auth/login' page. The issue arises because the application fails to properly validate a URL parameter, 'callbackUrl', which is used for redirection. This flaw allows an attacker to create a malicious link that, when clicked by an authenticated user, redirects them and executes arbitrary JavaScript in their browser. Such exploitation could result in credential theft, unauthorized actions on behalf of the user, and internal network pivoting if the user has access to other systems.
Users are advised to update to Homarr version 1.57.0 or later. For those maintaining versions prior to 1.57.0, it is recommended to validate and sanitize the 'callbackUrl' parameter before using it for redirection. This can be done by ensuring the URL is an absolute path within the same origin and does not contain dangerous schemes like 'javascript:'.
