CVE-2025-64522

Estado: AnalizadaAlta (7.6)—

Soft Serve is a self-hostable Git server for the command line. Versions prior to 0.11.1 have a SSRF vulnerability where webhook URLs are not validated, allowing repository administrators to create webhooks targeting internal services, private networks, and cloud metadata endpoints. Version 0.11.1 fixes the vulnerability.

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.

SSRF en webhooks (CWE-918) con acceso red pero PR:H permite atacantes autenticados explotar servicios internos y metadatos. Vector CVSS y descripción sustentan T1210 e impactos T1090 (proxy) + T1005 (acceso datos).

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.
