CVE-2025-54871

Estado: AnalizadaAlta (7.8)—

Electron Capture facilitates video playback for screen-sharing and capture. In versions 2.19.1 and below, the elecap app on macOS allows local unprivileged users to bypass macOS TCC privacy protections by enabling ELECTRON_RUN_AS_NODE. This environment variable allows arbitrary Node.js code to be executed via the -e flag, which runs inside the main Electron context, inheriting any previously granted TCC entitlements (such as access to Documents, Downloads, etc.). This issue is fixed in version 2.20.0.

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.

Vulnerabilidad local (AV:L) que permite a usuario sin privilegios ejecutar código Node.js arbitrario dentro del contexto de Electron heredando permisos TCC ya otorgados, escalando capacidades de acceso a datos sensibles.

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.
