Technical Analysis
CVE-2026-84659 affects Jenkins Script Security Plugin versions 1412.v7737b_3405f86 and earlier. The vulnerability arises because the method controlling the "Force the use of the sandbox globally in the system" setting does not enforce a permission check. This flaw allows attackers with low privileges to disable the sandbox globally by exploiting Stapler data binding, potentially weakening script execution restrictions.
Potential Impact
The vulnerability does not allow direct compromise of confidentiality or availability but impacts integrity by allowing attackers to disable sandbox enforcement. This could enable execution of untrusted scripts without sandbox restrictions, increasing risk of unauthorized code execution within Jenkins environments.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to Jenkins Script Security Plugin settings to trusted users only to reduce risk of exploitation.
