CVE-2025-31728Network attack vector

API key disclosure via unmasked configuration field

Published Apr 2, 2025 · Updated Apr 3, 2025

Sensitive-data exposure in Jenkins AsakusaSatellite Plugin 0.1.1 and earlier allows remote authenticated users to capture API keys. The job configuration form renders the stored AsakusaSatellite API key in an unmasked input field instead of concealing its value. Access to a configured job form and observation of the rendered page are required, exposing the key without granting direct configuration changes.
