AC:H reflects that exploitation requires a specific developer misconfiguration (non-existent serve_from path) outside attacker control; C:L captures read-only access to working-directory files with no integrity or availability impact.

Lifecycle Timeline
3DescriptionCVE.org
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.
AnalysisAI
Path traversal in the actix-files Rust crate (versions 0.6.9 and earlier) exposes arbitrary files from the application's working directory to unauthenticated remote attackers. When Files::new() receives a non-existent serve_from directory, the library silently substitutes an empty base path; subsequent requests join attacker-supplied filenames against this empty root, which Rust's canonicalize() resolves relative to the process working directory, enabling direct file disclosure. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires exactly one precondition: the application must call `actix_files::Files::new()` with a `serve_from` argument pointing to a directory path that does not exist on the filesystem at the time the actix server initializes. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:P/PR:N/UI:N/VC:L) characterizes this as network-exploitable and unauthenticated, with a low confidentiality impact and an explicit attack requirement (AT:P): exploitation is contingent on the developer having misconfigured `Files::new()` with a non-existent `serve_from` path, a condition beyond the attacker's control. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade actix-files to version 0.6.10, which is the vendor-released patch confirmed by advisory GHSA-8v2v-wjwg-vx6r at https://github.com/actix/actix-web/security/advisories/GHSA-8v2v-wjwg-vx6r. … Detailed patch versions, workarounds, and compensating controls in full report. |
