Detailsinfo

A vulnerability, which was classified as critical, was found in tw93 Pake up to 3.13.0. This affects the function download_file of the component Download File Command. The manipulation of the argument filename with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Pake before 3.13.1 joins the JavaScript-supplied filename for the download_file Tauri command onto the user's Downloads directory with no sanitization. A filename containing path traversal sequences (for example ../Library/LaunchAgents/com.evil.plist) or an absolute path resolves outside ~/Downloads. The command then fetches attacker-controlled content from the supplied URL (via Rust HTTP, not the browser) and writes it to that path. A script that can invoke the command can overwrite user-writable files and install persistence (macOS LaunchAgents, Linux autostart, Windows Startup), leading to code execution in the user account. All desktop apps generated from an affected Pake tree expose the same command.

The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2026-82635 since 08/30/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. It demands that the victim is doing some kind of user interaction. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1006 for this issue.

Upgrading to version 3.13.1 eliminates this vulnerability.
