Jenkins File Parameter Plugin 425.v3fa_801681b_5e and earlier allows writing files to arbitrary locations on the Jenkins controller file system through Stapler data binding, which can lead to remote code execution.
Articles & Coverage 2
AnalysisAI
Arbitrary file write to remote code execution in Jenkins File Parameter Plugin (versions ≤ 425.v3fa_801681b_5e) is achievable by any low-privilege authenticated Jenkins user through a Stapler data binding flaw. By crafting a build request with a path-traversal file parameter, an attacker can write attacker-controlled content to arbitrary locations on the Jenkins controller filesystem, enabling code execution by overwriting Groovy init scripts, SSH authorized_keys, or other sensitive files. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid Jenkins account with at minimum the permissions necessary to trigger a parameterized build (typically Job/Build or Job/Read plus Build). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.8 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) correctly reflects network-reachable exploitation by any authenticated user with no complexity barrier and no user interaction. … 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 the Jenkins File Parameter Plugin to the version identified as patching SECURITY-4093 in the official advisory at https://www.jenkins.io/security/advisory/2026-09-02/#SECURITY-4093. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Jenkins instances to identify those running File Parameter Plugin version 425.v3fa_801681b_5e or earlier, and restrict build-parameter edit permissions to senior administrators only. …
