Jenkins GitLab Plugin 1.9.16 and earlier allows overwriting the global GitLab connection configuration through Stapler data binding, allowing attackers to connect to an attacker-specified URL using GitLab API tokens already configured by administrators.
AnalysisAI
Configuration integrity compromise in Jenkins GitLab Plugin 1.9.16 and earlier enables authenticated low-privileged users to overwrite the global GitLab connection URL via Stapler data binding, redirecting GitLab API calls to attacker-controlled infrastructure. This causes Jenkins to transmit administrator-configured GitLab API tokens to the attacker's endpoint whenever a pipeline, webhook, or scheduled job triggers a GitLab API interaction. …

Vulnerability AssessmentAI
| Exploitation | Requires a valid Jenkins user account with at least low-level permissions - Overall/Read is the typical baseline sufficient for Stapler data binding access. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 5.4 Medium score is driven primarily by PR:L (authenticated low-privilege requirement), which is the principal limiting factor. … 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 | The primary fix is to upgrade Jenkins GitLab Plugin to a version beyond 1.9.16 via the Jenkins Update Center; consult the Jenkins security advisory at https://www.jenkins.io/security/advisory/2026-09-02/#SECURITY-4097 for the exact patched release, as the specific fixed version number is not stated in the available data. … Detailed patch versions, workarounds, and compensating controls in full report. |
