AnalysisAI
Unrestricted object instantiation in Jenkins 2.575 and earlier (LTS 2.568.1 and earlier) allows users holding Overall/Manage permission to instantiate arbitrary Java types through the project naming strategy configuration, including configuration objects intended exclusively for full administrators. This effectively breaks the permission boundary between Overall/Manage holders and full system administrators, enabling privilege escalation within the Jenkins controller. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to hold Overall/Manage permission on the target Jenkins instance - this is a mid-tier privilege typically delegated to infrastructure engineers or team leads, not anonymous or low-privilege users. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | No CVSS vector or EPSS score was provided in the available intelligence; risk must be inferred from the permission requirement and impact description. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade Jenkins to version 2.576 (weekly) or Jenkins LTS 2.568.2, as detailed in the official advisory at https://www.jenkins.io/security/advisory/2026-08-05/. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all Jenkins instances running version 2.575 or earlier (and LTS 2.568.1 or earlier) across your infrastructure. …
