The vulnerability identified as CVE-2025-67643 affects the Jenkins Redpen - Pipeline Reporter for Jira Plugin, specifically versions 1.054.v7b_9517b_6b_202 and earlier. The issue arises from improper path validation during the artifact upload process to Jira, which is part of the plugin's functionality to report pipeline results. Attackers who possess Item/Configure permissions within Jenkins can exploit this flaw to retrieve arbitrary files located in the Jenkins controller's workspace directory. This workspace typically contains build artifacts, source code, configuration files, and potentially sensitive credentials or tokens used during CI/CD processes. The lack of proper path sanitization means that crafted requests can traverse directories or specify unintended file paths, bypassing intended access controls. Although exploitation requires the attacker to have certain permissions, these are commonly granted to developers or automation accounts, increasing the risk. No CVSS score has been assigned yet, and no known exploits are publicly reported, but the vulnerability is publicly disclosed and considered serious due to the sensitive nature of the data exposed. The plugin is widely used in Jenkins environments that integrate with Jira for issue tracking and reporting, making this a relevant threat for organizations relying on these tools for software development and project management.

For European organizations, this vulnerability poses a significant risk to the confidentiality of sensitive project and build information. Exposure of workspace files could lead to leakage of proprietary source code, credentials, or configuration details, which attackers could leverage for further compromise or intellectual property theft. Organizations with strict data protection regulations, such as GDPR, may face compliance issues if sensitive personal or business data is exposed. The integrity of the CI/CD pipeline could also be undermined if attackers gain insights into build processes or inject malicious artifacts. Availability impact is limited but could arise if attackers manipulate or delete workspace files after gaining access. The threat is particularly relevant for sectors with high reliance on software development and agile project management, including finance, telecommunications, and critical infrastructure providers in Europe. The requirement for Item/Configure permissions means insider threats or compromised developer accounts are the most likely vectors, emphasizing the need for strict access control and monitoring.

Organizations should immediately audit and restrict Item/Configure permissions in Jenkins to only trusted users and service accounts. Until a patch is released, consider disabling the Jenkins Redpen - Pipeline Reporter for Jira Plugin if feasible. Monitor Jenkins controller workspace directories for unusual access patterns or file retrieval attempts. Implement network segmentation to limit access to Jenkins controllers and enforce strong authentication mechanisms such as multi-factor authentication for Jenkins users. Review and harden Jira integration configurations to minimize exposure. Once a vendor patch or update is available, apply it promptly to ensure proper path validation is enforced. Additionally, conduct regular security assessments of CI/CD pipelines and plugins to identify and remediate similar issues proactively. Employ logging and alerting on Jenkins and Jira to detect suspicious activities related to artifact uploads and downloads.
