CVE-2026-72814: actix-files before 0.6.10 Information Disclosure via Files

• Severity: medium (CVSS 6.3 v4.0)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.5% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-08-14 · updated 2026-10-29
• Weakness: CWE-22

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.
