CVE-2026-102826

Estado: En análisisAlta (8.1)—

simple-git, an interface for running git commands in any node.js application, enables applications to execute Git operations from JavaScript. Prior to 4.0.0, the default blockUnsafeOperationsPlugin does not completely reject configuration includes supplied through customArgs to git.clone(). The missing include.path classification permits Git to load an attacker-controlled configuration file, and the initial remediation does not cover includeIf.<condition>.path, allowing the same file-loading primitive through a conditional include.

Leer descripción completaMostrar menos

A loaded configuration can set an executable Git option such as core.sshCommand, which Git invokes during the clone operation with the privileges of the Node.js process. Exploitation requires the application to pass attacker-influenced custom arguments and requires an attacker-controlled file that the process can read. This issue is fixed in 4.0.0.

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.

Vulnerable node.js library permite ejecución remota de comandos vía git.clone() con argumentos no sanitizados (CWE-77/78). Atacante controla archivo config y ejecuta core.sshCommand con privilegios del proceso (AV:N, AC:H, sin autenticación requerida).

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.
