CVE-2025-53650: 
Java vulnerability analysis and mitigation

CVE-2025-53650 affects the Jenkins Credentials Binding Plugin versions 687.v619cb_15e923f and earlier. The vulnerability was discovered and disclosed on July 9, 2025, and involves improper masking of credentials in build log error messages. This security issue impacts the Jenkins automation server ecosystem, specifically the Credentials Binding Plugin which is used to handle sensitive credentials in build processes (Jenkins Advisory).

The vulnerability stems from the plugin's failure to properly mask (replace with asterisks) credentials that appear in exception error messages written to the build log. The issue has been assigned a Medium severity rating according to CVSS scoring metrics. The CVSS v3.1 base score is 7.3 (HIGH) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L (NVD, Jenkins Advisory).

The vulnerability could lead to the exposure of sensitive credentials through build log error messages. When exceptions occur during build processes, credentials that should be masked could be visible in plain text within the error messages, potentially exposing sensitive information to unauthorized users (Jenkins Advisory).

The vulnerability can be exploited when exception error messages containing credentials are generated during build processes. The exposure occurs through the build log, which may be accessible to users with access to the Jenkins system (Jenkins Advisory).

The vulnerability has been fixed in Credentials Binding Plugin version 687.689.v1a_f775332fc9. The updated version properly rethrows exceptions that contain credentials, ensuring that those credentials are masked in the error messages. Users are strongly advised to upgrade to this patched version to prevent credential exposure (Jenkins Advisory).
