The vulnerability identified as CVE-2025-53660 affects the Jenkins QMetry Test Management Plugin version 1.13 and earlier. This plugin integrates QMetry test management capabilities into Jenkins, a widely used automation server for continuous integration and continuous delivery (CI/CD). The core issue is that the plugin fails to mask QMetry Automation API keys on the job configuration form. API keys are sensitive credentials that grant access to automation and test management functions. When these keys are displayed in plaintext within the Jenkins job configuration interface, they become visible to anyone with access to the Jenkins UI or configuration files. This exposure significantly increases the risk of credential theft by malicious insiders or external attackers who have gained limited access to the Jenkins environment. The stolen API keys could then be used to manipulate test management data, execute unauthorized automation tasks, or pivot to other systems integrated with QMetry. Although there are no known exploits in the wild at the time of publication, the vulnerability represents a clear risk vector due to the sensitive nature of API keys and the common use of Jenkins in software development pipelines. The absence of a CVSS score suggests this is a newly disclosed issue, but the technical details indicate a confidentiality breach risk without direct impact on system availability or integrity by itself. The vulnerability does not require user interaction beyond viewing the configuration form, and exploitation requires at least some level of access to the Jenkins UI or configuration files, which may be restricted in well-managed environments.

For European organizations, the impact of this vulnerability can be significant, especially for those relying on Jenkins for CI/CD pipelines and using the QMetry Test Management Plugin. Exposure of API keys can lead to unauthorized access to test management systems, potentially allowing attackers to alter test results, inject malicious test scripts, or disrupt automated testing workflows. This can degrade software quality, delay releases, and introduce security risks downstream in the software supply chain. Additionally, if attackers leverage stolen API keys to access other integrated systems, this could lead to broader data breaches or operational disruptions. Organizations in regulated industries such as finance, healthcare, and critical infrastructure in Europe may face compliance risks if sensitive data is compromised. The vulnerability also raises insider threat concerns, as any user with Jenkins configuration access could inadvertently or maliciously expose API keys. Given the widespread use of Jenkins across European enterprises and public sector organizations, the risk of lateral movement and escalation within development environments is notable.

To mitigate this vulnerability, European organizations should immediately upgrade the Jenkins QMetry Test Management Plugin to a version where the API keys are properly masked or hidden in the job configuration form once such a patch is released. Until then, organizations should restrict access to Jenkins configuration interfaces strictly to trusted personnel and enforce the principle of least privilege. Implementing role-based access control (RBAC) and auditing access logs can help detect unauthorized viewing of sensitive configurations. Additionally, organizations should rotate any exposed API keys promptly and monitor for suspicious activity related to QMetry automation accounts. As a preventive measure, consider encrypting sensitive credentials and using Jenkins credentials plugins or vault integrations to manage secrets securely rather than embedding them directly in job configurations. Regular security reviews of CI/CD pipeline configurations and secrets management practices are recommended to reduce exposure risks.
