CVE-2026-57296: Vulnerability in Jenkins Project Jenkins External Workspace Manager Plugin
Jenkins External Workspace Manager Plugin 1.3.2 and earlier does not reject path traversal sequences in the custom workspace path provided to the exwsAllocate Pipeline step, allowing attackers with Item/Configure permission to read arbitrary files on the Jenkins controller file system, which can lead to remote code execution.
AI Analysis
Technical Summary
The Jenkins External Workspace Manager Plugin up to version 1.3.2 does not properly validate the custom workspace path input in the exwsAllocate Pipeline step, failing to reject path traversal sequences. This allows an attacker with Item/Configure permission to access arbitrary files on the Jenkins controller file system. Such unauthorized file access can escalate to remote code execution, posing a significant security risk to Jenkins environments using this plugin.
Potential Impact
Attackers with Item/Configure permission can read arbitrary files on the Jenkins controller file system, which may expose sensitive information. This unauthorized access can lead to remote code execution, compromising the integrity and availability of the Jenkins controller and potentially the entire CI/CD pipeline.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict Item/Configure permissions to trusted users only to reduce the risk of exploitation.
