CVE-2025-53661: Vulnerability in Jenkins Project Jenkins Testsigma Test Plan run Plugin
Jenkins Testsigma Test Plan run Plugin 1.6 and earlier does not mask Testsigma API keys displayed on the job configuration form, increasing the potential for attackers to observe and capture them.
AI Analysis
Technical Summary
CVE-2025-53661 is a security vulnerability identified in the Jenkins Testsigma Test Plan run Plugin version 1.6 and earlier. Jenkins is a widely used open-source automation server that facilitates continuous integration and continuous delivery (CI/CD). The Testsigma Test Plan run Plugin integrates Testsigma test plans into Jenkins jobs. The vulnerability arises because the plugin does not mask or obfuscate the Testsigma API keys when they are displayed on the Jenkins job configuration form. API keys are sensitive credentials that provide access to the Testsigma platform and potentially other integrated services. By displaying these keys in plaintext within the Jenkins UI, the plugin inadvertently exposes them to anyone with access to the Jenkins job configuration page. This exposure increases the risk that an attacker or unauthorized user who can view the job configuration could capture these keys and misuse them to gain unauthorized access to Testsigma resources or execute malicious actions within the CI/CD pipeline. Although no known exploits are currently reported in the wild, the vulnerability represents a significant security risk due to the sensitive nature of API keys and the common practice of sharing Jenkins access among multiple users or teams. The lack of a CVSS score indicates that the vulnerability has not yet been formally scored, but the technical details confirm that the issue is related to credential exposure through insufficient masking in the UI.
Potential Impact
For European organizations, this vulnerability poses a risk primarily to the confidentiality and integrity of their CI/CD environments and associated test automation workflows. If an attacker gains access to exposed API keys, they could manipulate test plans, inject malicious tests, or extract sensitive project information. This could lead to unauthorized access to internal systems, disruption of automated testing processes, and potential compromise of software delivery pipelines. Organizations handling sensitive or regulated data (e.g., financial, healthcare, or critical infrastructure sectors) could face compliance violations under GDPR or other data protection regulations if such credentials are leaked or misused. The risk is amplified in environments where Jenkins access controls are lax or where multiple users share access to job configurations. Additionally, the exposure of API keys could facilitate lateral movement within the network or enable attackers to pivot to other integrated systems, increasing the overall attack surface.
Mitigation Recommendations
To mitigate this vulnerability, European organizations should take the following specific actions: 1) Immediately upgrade the Jenkins Testsigma Test Plan run Plugin to a version where this issue is fixed once available. If no patch is currently available, consider disabling the plugin or restricting its usage until a fix is released. 2) Review and tighten access controls on Jenkins job configuration pages to ensure that only trusted and authorized personnel can view or modify job configurations. Implement role-based access control (RBAC) and audit access logs regularly. 3) Rotate any exposed Testsigma API keys immediately to invalidate potentially compromised credentials. 4) Implement secrets management best practices by avoiding storing API keys directly in Jenkins job configurations; instead, use Jenkins credentials plugins or secure vault integrations that mask sensitive data. 5) Educate development and DevOps teams about the risks of credential exposure and enforce policies to minimize unnecessary sharing of Jenkins access. 6) Monitor Jenkins logs and network traffic for suspicious activity that could indicate misuse of exposed API keys. 7) Consider network segmentation to limit the impact of compromised credentials and reduce lateral movement opportunities.
