CVE-2026-57280: Vulnerability in Jenkins Project Jenkins Script Security Plugin
Jenkins Script Security Plugin 1402.v94c9ce464861 and earlier does not intercept the implicit type casts applied to the elements of typed for-each loops in sandboxed Groovy scripts, allowing attackers able to provide such scripts to invoke arbitrary constructors and bypass the sandbox protection.
AI Analysis
Technical Summary
The Jenkins Script Security Plugin up to version 1402.v94c9ce464861 fails to intercept implicit type casts applied to elements in typed for-each loops in sandboxed Groovy scripts. This oversight permits attackers able to provide Groovy scripts to invoke arbitrary constructors, thereby bypassing the sandbox restrictions intended to limit script capabilities and potentially leading to unauthorized code execution within the Jenkins environment.
Potential Impact
Attackers who can supply Groovy scripts to Jenkins instances using the vulnerable Script Security Plugin can bypass sandbox protections and invoke arbitrary constructors. This can lead to execution of unauthorized code within the Jenkins environment, potentially compromising the integrity and security of the Jenkins server and its build processes.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict script submission privileges to trusted users only and consider disabling script approval or sandbox features if feasible. Monitor Jenkins security advisories for updates regarding patches or official mitigations.
