Jenkins 2.579 and earlier, LTS 2.568.2 and earlier does not escape map keys when serializing objects as JSON and Python through its REST API, allowing attackers able to control map property names to inject arbitrary fields into JSON and Python API responses.
AnalysisAI
Jenkins REST API in versions 2.579 and earlier (LTS 2.568.2 and earlier) fails to escape map keys during JSON and Python serialization, enabling authenticated users who can control map property names to inject arbitrary fields into API responses consumed by downstream tooling or users. The flaw (CWE-116, improper output encoding) is rated CVSS 4.3 Medium with integrity-only impact and requires low-privilege authenticated access. …

Vulnerability AssessmentAI
| Exploitation | Requires authenticated access with at least low-privilege Jenkins permissions (PR:L per CVSS vector) sufficient to create or configure an object whose name or map key is reflected in REST API responses - for example, job parameter names, credential IDs, or plugin-managed map-keyed entities. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.3 Medium rating (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N) accurately reflects a bounded but real risk: exploitation requires authenticated network access with at least low-privilege Jenkins permissions (PR:L), limiting opportunistic attacks. … 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 weekly release 2.580 or LTS release 2.568.3, both confirmed as fix versions by the vendor advisory (https://www.jenkins.io/security/advisory/2026-09-02/#SECURITY-3879). … Detailed patch versions, workarounds, and compensating controls in full report. |
