Root Cause Analysis
The vulnerability stems from the client secret being transmitted in plaintext during configuration form submissions. Jenkins plugins typically handle global configuration via a Descriptor
/GlobalConfiguration
class. The configure
method in such classes processes form data. In pre-1.2.0 versions, the client secret would have been read directly from unencrypted request parameters (e.g., request.getParameter('clientSecret')
) before being encrypted for disk storage. The patched version (1.2.0) likely introduced encryption before transmission, which implies the original function lacked this protection. The configure
method is the logical point where plaintext transmission would occur, aligning with the CWE-256/CWE-522 descriptions.
