Lifecycle Timeline
5DescriptionCVE.org
In Jenkins 2.579 and earlier, LTS 2.568.2 and earlier, the build CLI command does not check the Item/Cancel permission when using the -s flag to cancel a build triggered to wait for completion, allowing attackers with Item/Build permission to cancel builds started by other users.
AnalysisAI
Missing authorization in Jenkins' CLI build command allows authenticated low-privileged users to cancel builds they did not initiate. When invoking the build CLI command with the -s flag (wait-for-completion mode), Jenkins 2.579 and earlier and LTS 2.568.2 and earlier skip the required Item/Cancel permission check, enabling any user holding only Item/Build permission to abort in-flight builds owned by other users. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated Jenkins account with `Item/Build` permission on the targeted job - unauthenticated exploitation is not possible (PR:L in CVSS). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 3.1 vector (AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:L, score 4.2) is well-calibrated. … 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 to Jenkins 2.580 (weekly channel) or Jenkins LTS 2.568.3, which introduce the missing `Item/Cancel` permission check on the CLI build cancel code path. … Detailed patch versions, workarounds, and compensating controls in full report. |
