Arbitrary file write via unsanitized download filename
Published Aug 30, 2026 · Updated Aug 30, 2026
Path traversal in Pake before 3.13.1 allows remote attackers to write arbitrary files through a crafted download filename. The download_file Tauri command joins the JavaScript-supplied filename to the Downloads directory without rejecting traversal segments or absolute paths, then fetches attacker-controlled content and writes it to the resolved location. Exploitation requires script access to the exposed command and grants writes only to paths available to the current user, including per-user startup locations.

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.
