CVE-2026-33510
HighSummary
W Homarr, przed wersją 1.57.0, odkryto podatność typu Cross-Site Scripting (XSS) opartą na DOM w stronie /auth/login. Aplikacja niewłaściwie ufa parametrowi URL (callbackUrl), co pozwala atakującemu na stworzenie złośliwego linku, który po otwarciu przez uwierzytelnionego użytkownika wykonuje dowolny kod JavaScript w kontekście jego przeglądarki.
Risk Assessment
Podatność ta może prowadzić do kradzieży poświadczeń, przejęcia wewnętrznej sieci oraz nieautoryzowanych działań wykonywanych w imieniu ofiary, co stwarza poważne zagrożenie dla bezpieczeństwa organizacji.
Recommendation
Zaleca się aktualizację aplikacji do wersji 1.57.0 lub nowszej, aby usunąć tę podatność oraz zminimalizować ryzyko ataków XSS.

Original NVD description (English source)
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.
