A missing permission check in Jenkins Pipeline: Build Step Plugin 599.v4b_67ea_11b_152 and earlier causes downstream builds awaited by the waitForBuild step when the propagateAbort parameter is used to be canceled even when the build's authentication lacks Item/Cancel permission on the downstream job.
AnalysisAI
Unauthorized build cancellation in Jenkins Pipeline: Build Step Plugin 599.v4b_67ea_11b_152 and earlier allows any authenticated low-privilege user to cancel downstream pipeline builds they should not be able to touch. When a pipeline uses the waitForBuild step with the propagateAbort parameter enabled, aborting the upstream build propagates a cancel signal to downstream jobs without verifying whether the caller holds the required Item/Cancel permission on those downstream jobs. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires: (1) the attacker is authenticated to Jenkins with at least Job/Build (or equivalent) permission on an upstream pipeline job - no unauthenticated path exists; (2) the upstream pipeline uses the `waitForBuild` step with the `propagateAbort` parameter set to `true` - pipelines that do not use this parameter or set `propagateAbort: false` are unaffected; (3) a downstream build is actively awaited by that step at the time the upstream pipeline is aborted. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L (5.4 Medium) accurately reflects the attack surface: network-reachable, no special conditions, but requires at least low-level authentication. … 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 | Apply the patched version of Jenkins Pipeline: Build Step Plugin released by the Jenkins project, as detailed in the security advisory at https://www.jenkins.io/security/advisory/2026-09-02/#SECURITY-3870. … Detailed patch versions, workarounds, and compensating controls in full report. |
