File disclosure via unchecked asset path join
Published Jan 20, 2021 · Updated Aug 3, 2024
Path traversal in Keymaker before 0.2.0 allows remote authenticated users to read files outside its assets directory through crafted requests. The assets endpoint passes an unchecked request path to Rust's path join operation without enforcing an allowed extension or directory boundary. Low-privileged network access is required, and the bounded consequence is disclosure of files readable by the server process.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
