Jenkins Parameterized Remote Trigger Plugin 3.2.2 and earlier stores tokens unencrypted in job config.xml files on the Jenkins controller where they can be viewed by users with Item/Extended Read permission or access to the Jenkins controller file system.
AnalysisAI
Plaintext token storage in Jenkins Parameterized Remote Trigger Plugin 3.2.2 and earlier exposes authentication tokens to any Jenkins user holding Item/Extended Read permission or to anyone with direct access to the Jenkins controller filesystem. Tokens written to job config.xml files are readable without decryption, potentially allowing lower-privileged users to impersonate legitimate remote-trigger callers and invoke builds on downstream Jenkins instances. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid Jenkins user account with at minimum Item/Extended Read permission on a job that has the Parameterized Remote Trigger Plugin configured with a token, or direct read access to the Jenkins controller filesystem (e.g., shared hosting, compromised adjacent service, or insider access). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.3 score (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N) accurately reflects a low-to-medium severity credential exposure with a network-accessible attack vector but a privilege prerequisite. … 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 remediation is to upgrade Jenkins Parameterized Remote Trigger Plugin to the version designated as fixed in the Jenkins security advisory at https://www.jenkins.io/security/advisory/2026-09-02/#SECURITY-3800; the exact patched release version is not specified in the available input data and should be confirmed directly from the advisory before upgrading. … Detailed patch versions, workarounds, and compensating controls in full report. |
