FKIE_CVE-2026-82635

Vulnerability from fkie_nvd - Published: 2026-08-30 13:16 - Updated: 2026-09-04 20:32

Severity

8.8 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H

Summary

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.

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
