CVE-2025-43929

Estado: AnalizadaAlta (7.8)—

open_actions.py in kitty before 0.41.0 does not ask for user confirmation before running a local executable file that may have been linked from an untrusted document (e.g., a document opened in KDE ghostwriter).

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.

Vector AV:L UI:R indica explotación en el cliente (T1203): usuario abre documento en editor untrusted; kitty ejecuta ejecutable local vinculado sin confirmación previa, logrando ejecución de código arbitrario (T1059) y potencial lectura de datos sensibles (T1005).

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.
