AI Analysis
Technical Summary
CVE-2026-57295 is a CSRF vulnerability in Jenkins EC2 Fleet Plugin versions 4.2.3.539.v8fedff2a_81c3 and earlier. Exploitation enables an attacker to leverage attacker-specified credentials IDs, obtained through other methods, to connect to an attacker-controlled URL and capture AWS credentials stored within Jenkins. The plugin is a cloud service, and the vendor typically handles patching server-side.
Potential Impact
Successful exploitation can lead to unauthorized access to AWS credentials stored in Jenkins, which may result in credential theft and potential misuse of AWS resources. This poses a significant security risk to environments relying on these credentials for cloud operations.
Mitigation Recommendations
A patch is available for this vulnerability. Since the Jenkins EC2 Fleet Plugin is a cloud-hosted service, the vendor manages remediation server-side. Users should verify with the vendor advisory that their service instance has been updated to address this vulnerability.
