CVE-2026-33213

Redash is a package for data visualization and sharing. From 5.0.2 to 26.3.0, the get_next_path() function in Redash's authentication module stripped the scheme and netloc from user-supplied next parameters but did not normalize multiple leading slashes, allowing a crafted login URL such as /login?next=////evil.com to redirect users to an external attacker-controlled site after authentication.

Summary		(es) Redash es un paquete para visualización y compartición de datos. Desde la versión 5.0.2 hasta la 26.3.0, la función get_next_path() en el módulo de autenticación de Redash eliminaba el esquema y el netloc de los parámetros ’next’ proporcionados por el usuario, pero no normalizaba múltiples barras diagonales iniciales, lo que permitía que una URL de inicio de sesión manipulada como /login?next=////evil.com redirigiera a los usuarios a un sitio externo controlado por el atacante después de la autenticación.
