CVE-2025-53637

Estado: AnalizadaAlta (8)—

Meshtastic is an open source mesh networking solution. The main_matrix.yml GitHub Action is triggered by the pull_request_target event, which has extensive permissions, and can be initiated by an attacker who forked the repository and created a pull request. In the shell code execution part, user-controlled input is interpolated unsafely into the code. If this were to be exploited, attackers could inject unauthorized code into the repository. This vulnerability is fixed in 2.6.6.

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.

UI:R (requiere interacción del usuario para revisar/mergear PR) → T1203. CWE-78 + inyección en shell → T1059. Manipulación de código en repositorio → T1565.002.

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.
