CVE-2025-53676 is a security vulnerability identified in the Jenkins Xooa Plugin version 0.0.7 and earlier. The vulnerability arises because the plugin stores the Xooa Deployment Token unencrypted in the global configuration file on the Jenkins controller. This token is a sensitive credential used for deployment purposes within the Xooa platform integrated with Jenkins. Since the token is stored in plaintext, any user or process with access to the Jenkins controller's file system can read this token. This exposure can lead to unauthorized access to deployment functions or services that rely on the token, potentially allowing attackers to manipulate deployments, inject malicious code, or disrupt continuous integration/continuous deployment (CI/CD) pipelines. The vulnerability does not require user interaction but does require file system access to the Jenkins controller, which is typically restricted but may be accessible to certain internal users or compromised accounts. There is no CVSS score assigned yet, and no known exploits in the wild have been reported as of the publication date. The vulnerability affects Jenkins Xooa Plugin versions up to 0.0.7, and no patch links have been provided at this time.

For European organizations, this vulnerability can have significant implications, especially for those heavily reliant on Jenkins for CI/CD pipelines and using the Xooa Plugin for blockchain or deployment automation. Exposure of the deployment token can lead to unauthorized deployments, potentially injecting malicious code into production environments or disrupting software delivery processes. This can compromise the integrity and availability of critical applications and services. Additionally, if the deployment token grants access to blockchain or other sensitive infrastructure, confidentiality breaches may occur. Organizations in sectors such as finance, healthcare, and critical infrastructure, which often use Jenkins for automation, could face operational disruptions and compliance issues under regulations like GDPR if sensitive data or systems are compromised. The risk is amplified in environments where multiple users have access to the Jenkins controller file system or where insider threats exist.

To mitigate this vulnerability, European organizations should: 1) Immediately restrict file system access to the Jenkins controller to only trusted administrators and service accounts, minimizing the risk of unauthorized token exposure. 2) Upgrade the Jenkins Xooa Plugin to a version that addresses this vulnerability once available; if no patch is yet released, monitor vendor advisories closely. 3) Rotate the Xooa Deployment Token to invalidate any potentially exposed tokens and generate new tokens with minimal required privileges. 4) Implement encryption or secure storage mechanisms for sensitive tokens and credentials within Jenkins, such as using Jenkins credentials plugin or external secrets management solutions (e.g., HashiCorp Vault). 5) Audit Jenkins controller access logs and file system permissions regularly to detect unauthorized access attempts. 6) Consider isolating Jenkins controllers in secure network segments with strict access controls to reduce exposure. 7) Educate DevOps and security teams about the risks of storing sensitive tokens in plaintext and enforce secure credential management policies.
