CVE-2026-47878

Estado: AnalizadaAlta (7.3)—

DefaultExecutionContextSerializer, used by default in Spring Batch's JDBC job repository, passes Base64-decoded bytes directly to ObjectInputStream.readObject() without an ObjectInputFilter that restricts types to a trusted class allowlist. Spring Batch 6.0.0 - 6.0.4 Spring Batch 5.2.6 and earlier

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.

Desserialización insegura (CWE-502) en JDBC accesible remotamente sin autenticación (AV:N/PR:N). ObjectInputStream.readObject() sin filtrado permite RCE arbitrario; acceso de red sin privilegios = T1190. Impacto: ejecución de código (T1059) y escalada si contexto de batch tiene privilegios elevados.

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.
