{"id":"UBUNTU-CVE-2026-72814","details":"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.","modified":"2026-10-17T12:59:35.853838875Z","published":"2026-08-14T12:16:00Z","upstream":["CVE-2026-72814"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-72814"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-72814"},{"type":"REPORT","url":"https://github.com/actix/actix-web/security/advisories/GHSA-8v2v-wjwg-vx6r"},{"type":"REPORT","url":"https://www.vulncheck.com/advisories/actix-web-before-information-disclosure-via-files"}],"affected":[{"package":{"name":"rust-actix-files","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/rust-actix-files?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.6.10-1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.6.10-1","binary_name":"librust-actix-files-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-72814.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N"},{"type":"Ubuntu","score":"medium"}]}
