Summary
by MITRE • 12/10/2025
Jenkins Redpen - Pipeline Reporter for Jira Plugin 1.054.v7b_9517b_6b_202 and earlier does not correctly perform path validation of the workspace directory while uploading artifacts to Jira, allowing attackers with Item/Configure permission to retrieve files present on the Jenkins controller workspace directory.

The vulnerability identified as CVE-2025-67643 affects the Jenkins Redpen - Pipeline Reporter for Jira plugin version 1.054.v7b_9517b_6b_202 and earlier releases. This issue represents a critical path traversal flaw that undermines the security boundaries between Jenkins agents and the controller workspace. The vulnerability specifically manifests during artifact upload operations to Jira, where the plugin fails to properly validate the workspace directory paths. This technical weakness creates a scenario where authenticated attackers with minimal privileges can exploit the system to access sensitive files stored within the Jenkins controller's workspace directory. The flaw essentially allows unauthorized file retrieval through a seemingly legitimate plugin functionality that should only operate within defined boundaries.
The technical implementation of this vulnerability stems from inadequate input validation mechanisms within the plugin's artifact handling code. When the plugin processes workspace artifacts for Jira reporting, it does not sufficiently sanitize or validate the paths that specify where files should be retrieved from the controller's workspace. This path validation failure creates an opportunity for attackers to manipulate the path traversal behavior and access files that should remain protected within the Jenkins controller environment. The vulnerability operates at the intersection of inadequate access controls and improper path validation, creating a vector for information disclosure that bypasses normal security restrictions. This type of flaw commonly maps to CWE-22 Path Traversal and CWE-79 Improper Neutralization of Input During Web Page Generation, where the plugin fails to properly sanitize user-supplied paths before using them in file operations.
The operational impact of this vulnerability extends beyond simple information disclosure, as it provides attackers with potential access to sensitive build artifacts, source code repositories, configuration files, and other workspace contents that may contain credentials, proprietary data, or system information. Attackers with Item/Configure permissions can leverage this vulnerability to extract files from the Jenkins controller workspace, potentially gaining access to build scripts, environment variables, or other sensitive materials that could be used for further exploitation. The implications are particularly severe in environments where Jenkins controllers host multiple projects with varying security requirements, as a single compromised plugin instance could provide access to multiple project workspaces. This vulnerability effectively undermines the principle of least privilege and creates a persistent threat vector for attackers who can obtain minimal configuration permissions within Jenkins.
Mitigation strategies for this vulnerability should focus on immediate plugin version updates to the latest secure release that addresses the path validation issue. Organizations should also implement additional access controls and privilege restrictions to minimize the impact of potential exploitation, ensuring that only trusted users have Item/Configure permissions. Network segmentation and monitoring of Jenkins controller access patterns can help detect anomalous file access attempts that might indicate exploitation of this vulnerability. Security teams should also review and validate the workspace directory structure to ensure that sensitive files are not unnecessarily exposed through the plugin's artifact handling mechanisms. The remediation process should include comprehensive testing to verify that the updated plugin properly validates all workspace paths and that no bypass opportunities remain. Regular security assessments of Jenkins plugins and continuous monitoring for similar path traversal vulnerabilities in other components will help maintain overall system security posture. This vulnerability highlights the importance of proper input validation and access control implementation in plugin architectures and aligns with ATT&CK technique T1078 Valid Accounts and T1566 Phishing as it demonstrates how legitimate plugin functionality can be exploited for unauthorized access to system resources.
