CVE-2025-31728: 
Java vulnerability analysis and mitigation

Jenkins AsakusaSatellite Plugin 0.1.1 and earlier contains a security vulnerability (CVE-2025-31728) where AsakusaSatellite API keys are displayed unmasked on the job configuration form. This vulnerability was discovered and disclosed on April 2, 2025, affecting all versions of the AsakusaSatellite Plugin up to and including version 0.1.1 (Jenkins Advisory).

The vulnerability has been assigned a CVSS v3.1 Base Score of 5.5 (Medium) with the vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:L/A:L. The issue stems from the plugin's failure to implement proper masking of API keys in the job configuration interface, which exposes sensitive credentials to potential observation (NVD).

The vulnerability increases the potential for attackers to observe and capture AsakusaSatellite API keys when displayed in the job configuration form. This exposure of sensitive credentials could lead to unauthorized access to AsakusaSatellite services (Jenkins Advisory).

The vulnerability requires an attacker to have access to the Jenkins job configuration interface where they can view the unmasked API keys. The attack vector is network-accessible and requires low attack complexity, though it does need low privileges and user interaction (NVD).

As of the advisory's publication date, there is no fix available for this vulnerability in the AsakusaSatellite Plugin. Users should implement additional security controls to restrict access to the job configuration interface and monitor for potential unauthorized access to API keys (Jenkins Advisory).
