Doc Text:
A flaw was found in Jenkins Script Security Plugin. This vulnerability allows attackers who can provide sandboxed Groovy scripts to bypass security sandbox protections. By exploiting a failure to properly intercept implicit type casts in typed for-each loops, an attacker can invoke arbitrary constructors, potentially leading to arbitrary code execution within the Jenkins environment.

Description OSIDB Bzimport 2026-06-24 14:02:32 UTC
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.
