CVE-2026-70436: Vulnerability in Jenkins Project Jenkins External Workspace Manager Plugin
CVE-2026-70436 is a vulnerability in the Jenkins External Workspace Manager Plugin versions 1.4.1 and earlier. The issue involves missing or improper permission checks when accessing externally-managed workspaces through the workspace browser. This flaw allows attackers with Overall/Read permission to read files in workspaces they should not have access to.
AI Analysis
Technical Summary
The Jenkins External Workspace Manager Plugin up to version 1.4.1 suffers from a permission check vulnerability. Versions 1.4.0 and earlier do not perform any permission check, while version 1.4.1 performs an improper permission check when granting access to externally-managed workspaces. This allows users with Overall/Read permission to bypass intended access controls and read unauthorized workspace files.
Potential Impact
Attackers with Overall/Read permission can read files in workspaces they are not authorized to access, potentially exposing sensitive information stored in those workspaces. This could lead to information disclosure within Jenkins environments using the affected plugin versions.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict Overall/Read permissions to trusted users only to reduce risk. Monitor official Jenkins Project communications for updates and apply any released patches promptly.
