CVE-2023-50777Network attack vector

Authentication token disclosure via unmasked job configuration field

Published Dec 13, 2023 · Updated May 22, 2025

Information disclosure in Jenkins PaaSLane Estimate Plugin 1.0.4 and earlier allows remote authenticated users to capture tokens. The job configuration form renders the stored PaaSLane authentication token in an unmasked input field, exposing its full value to anyone who can open the form. Ability to open a job configuration form is required, and the reported consequence is token disclosure rather than data modification or service interruption.
