CVE-2026-92124

Estado: AnalizadaAlta (8.8)—

Jenkins Script Security Plugin 1415.v9a_f9b_3a_c253d and earlier checks the operations Groovy will perform with the elements it reads from a collection that a sandboxed script casts to another type but performs the cast on the collection itself, allowing attackers with permission to define and run sandboxed scripts, including Pipelines, to bypass the sandbox protection and execute arbitrary code in the context of the Jenkins controller JVM.

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.

Bypass de sandbox en Jenkins mediante casting de colecciones en Groovy. AV:N requiere PR:L (Jenkins autenticado) y permite ejecución arbitraria de código en el controlador.

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.
