Estado: AnalizadaAlta (7.1)—

Soft Serve is a self-hostable Git server for the command line. From version 0.6.0 to before version 0.11.6, an authorization flaw in repo import allows any authenticated SSH user to clone a server-local Git repository, including another user's private repo, into a new repository they control. This issue has been patched in version 0.11.6.

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.

Acceso remoto con privilegios (PR:L) a servidor Git local (Soft Serve). Clonación no autorizada de repos privados = lectura de datos sensibles (T1005). CWE-862 sugiere escalada de acceso (T1078).

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.
