CVE-2026-100257

Estado: AnalizadaMedia (4.3)—

In JetBrains YouTrack before 2026.2.18991 sSRF via stored XHTML injection was possible during PDF export

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 vía inyección XHTML almacenada en exportación PDF (CWE-918) requiere autenticación (PR:L) pero permite acceso a recursos internos (T1090). YouTrack almacena el payload en XHTML, derivando en impacto de integridad.

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.
