In JetBrains YouTrack before 2026.2.18991 stored SMTP server credentials could be disclosed by changing the server host

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.

Requiere acceso remoto con privilegios altos (PR:H) a YouTrack para modificar configuración SMTP y extraer credenciales almacenadas (CWE-522). Impacto: obtención de secretos de infraestructura.

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.
