CVE-2025-64481

Datasette is an open source multi-tool for exploring and publishing data. In versions 0.65.1 and below and 1.0a0 through 1.0a19, deployed instances of Datasette include an open redirect vulnerability. Hits to the path //example.com/foo/bar/ (the trailing slash is required) will redirect the user to https://example.com/foo/bar. This problem has been patched in both Datasette 0.65.2 and 1.0a21. To workaround this issue, if Datasette is running behind a proxy, that proxy could be configured to replace // with / in incoming request URLs.

Summary		(es) Datasette es una multiherramienta de código abierto para explorar y publicar datos. En las versiones 0.65.1 e inferiores y de la 1.0a0 a la 1.0a19, las instancias desplegadas de Datasette incluyen una vulnerabilidad de redirección abierta. Las solicitudes a la ruta //example.com/foo/bar/ (la barra final es obligatoria) redirigirán al usuario a HTTPS://example.com/foo/bar. Este problema ha sido parcheado tanto en Datasette 0.65.2 como en 1.0a21. Para aplicar una solución alternativa a este problema, si Datasette se está ejecutando detrás de un proxy, ese proxy podría configurarse para reemplazar // por / en las URL de las solicitudes entrantes.
