CVE-2026-82635

Estado: AnalizadaAlta (8.8)—

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.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Ejecución en cliente: Pake requiere interacción del usuario (UI:R) para invocar el comando JavaScript. Path traversal + sobrescritura de archivos de persistencia (LaunchAgents, autostart) permite ejecutar código en la cuenta del usuario.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
