CVE-2025-12120
Lite XL versions 2.1.8 and prior automatically execute the .lite_project.lua file when opening a project directory, without prompting the user for confirmation. The .lite_project.lua file is intended for project-specific configuration but can contain executable Lua logic. This behavior could allow execution of untrusted Lua code if a user opens a malicious project, potentially leading to arbitrary code execution with the privileges of the Lite XL process.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H
- Puntuación base: 7.3
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.33%
- Percentil entre todas las CVEs puntuadas: 24
- Fecha de la puntuación: 6/10/2026
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.
- Explotación
T1203Exploitation for Client Executionexecution85 % - Impacto principal
T1059Command and Scripting Interpreterexecution90 %
Requiere interacción del usuario (UI:R) al abrir un directorio de proyecto malicioso. El archivo .lite_project.lua se ejecuta automáticamente sin confirmación, permitiendo ejecución arbitraria de código Lua con privilegios del proceso.
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.
