Doc Text:
A flaw was found in actix-files. When a non-existing folder is provided as the `serve_from` argument to `Files::new()`, the service incorrectly resolves request paths as relative to the application's working directory. This allows an attacker to access unintended files, leading to information disclosure.

Description OSIDB Bzimport 2026-08-14 11:58:08 UTC 
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.
