CVE-2026-49374

Estado: AnalizadaAlta (7.6)—

In JetBrains TeamCity before 2026.1 improper permission checks exposed build configuration parameters

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.

AV:N/PR:L requiere acceso autenticado a servicio remoto (T1210). CWE-862 (permisos impropisos) expone parámetros de configuración permitiendo reutilizar credenciales/tokens (T1078) y acceso a datos sensibles (T1552.007).

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.
