CVE-2026-72814

Full vulnerability record from the local CVENow database.

Description

The actix-files crate (actix_files) before version 0.6.10 contains an information exposure vulnerability. When a non-existing folder is passed as the serve_from argument to Files::new(), the mount path defaults to an empty path; the service then joins the request path with this empty path and canonicalizes it, causing Rust to resolve it as a relative path. As a result, an attacker can request paths that resolve relative to the application's working directory and access unintended files.

Cuando se pasa una carpeta inexistente como argumento serve_from a Files::new(), la ruta de montaje por defecto es una ruta vacía; el servicio luego une la ruta de la solicitud con esta ruta vacía y la canoniza, lo que hace que Rust la resuelva como una ruta relativa. Como resultado, un atacante puede solicitar rutas que se resuelven de forma relativa al directorio de trabajo de la aplicación y acceder a archivos no deseados."
