CVE-2026-84670

Estado: Pendiente de análisisAlta (8.8)—

Jenkins Performance Plugin 1015.v09ca_52b_3370e and earlier does not restrict the classes that can be instantiated when deserializing cached performance reports stored in the build directory on the Jenkins controller, allowing attackers with Item/Configure permission to execute arbitrary code on the Jenkins controller.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Puntuación base: 8.8
