CVE-2026-57281
Jenkins Script Security Plugin 1402.v94c9ce464861 and earlier does not reject Groovy AST transformation annotations carrying an extensions member, allowing attackers able to run sandboxed Groovy scripts to execute code outside the sandbox if a suitable script is present on the classpath of the component that evaluates the script.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H
- Puntuación base: 7.5
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.92%
- Percentil entre todas las CVEs puntuadas: 59
- Fecha de la puntuación: 4/10/2026
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

- Explotación
T1210Exploitation of Remote Serviceslateral movement75 % - Impacto principal
T1059Command and Scripting Interpreterexecution80 % - Impacto secundario
T1068Exploitation for Privilege Escalationprivilege escalation70 %
Vulnerabilidad en Jenkins remota (AV:N, PR:L) que bypassa sandbox Groovy permitiendo ejecución de código no restringido fuera del sandbox. Escalada implícita al ejecutar código con 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.
