CVE-2025-53673 is a security vulnerability identified in version 1.0 of the Jenkins Sensedia Api Platform tools Plugin. This plugin integrates Jenkins with the Sensedia API Manager, facilitating API management tasks within Jenkins pipelines. The vulnerability arises because the plugin stores the Sensedia API Manager integration token in an unencrypted form within the global configuration file on the Jenkins controller. This token is a sensitive credential that grants access to the API Manager, and storing it unencrypted on disk exposes it to any user who has access to the Jenkins controller's file system. Since Jenkins controllers often run with elevated privileges and are central to continuous integration/continuous deployment (CI/CD) workflows, unauthorized access to this token could allow attackers to manipulate API configurations, exfiltrate sensitive data, or disrupt API services. The vulnerability does not require user interaction but does require file system access to the Jenkins controller, which may be limited to administrators or users with elevated permissions. No known exploits are currently reported in the wild, and no CVSS score has been assigned yet. However, the exposure of sensitive tokens in plaintext is a recognized security risk that can lead to privilege escalation and lateral movement within an organization's infrastructure.

For European organizations, this vulnerability poses a significant risk to the security of their API management infrastructure if they use Jenkins with the Sensedia Api Platform tools Plugin. Compromise of the integration token could allow attackers to gain unauthorized access to API management functions, potentially leading to data breaches, service disruptions, or unauthorized API modifications. Given the critical role of APIs in digital services, especially in sectors like finance, healthcare, and government within Europe, exploitation could result in operational downtime, regulatory non-compliance (e.g., GDPR violations due to data exposure), and reputational damage. Additionally, since Jenkins is widely used in software development pipelines, attackers could leverage this vulnerability to insert malicious code or disrupt deployment processes, amplifying the impact. The risk is heightened in environments where Jenkins controllers are shared or have multiple users with file system access, increasing the likelihood of token exposure.

To mitigate this vulnerability, organizations should immediately upgrade to a patched version of the Jenkins Sensedia Api Platform tools Plugin once available. Until a patch is released, organizations should restrict file system access to the Jenkins controller to only trusted administrators and implement strict access controls and monitoring on the Jenkins server. Encrypting sensitive configuration files or using Jenkins credentials plugins to securely store tokens rather than plaintext files is recommended. Additionally, rotating the Sensedia API Manager integration token regularly and revoking any tokens suspected to be exposed can reduce risk. Implementing network segmentation to limit access to the Jenkins controller and auditing Jenkins logs for unusual access patterns can help detect potential exploitation attempts. Finally, organizations should review their CI/CD pipeline security posture to ensure that sensitive credentials are never stored in plaintext and that least privilege principles are enforced.
