Security readout for executives and security teams
Plain-English summary
Jenkins Openstack Cloud Plugin 2.35 and earlier could expose stored Jenkins credentials. A user who already has Jenkins Overall/Read access and separately knows credential IDs could make Jenkins connect to a URL they control and capture secrets.
Executive priority
Prioritize affected Jenkins systems that hold production, cloud, or deployment credentials. The issue is plugin-specific and access-gated, but credential exposure from CI infrastructure can create material downstream compromise risk.
Technical view
The vulnerability is in multiple Openstack Cloud Plugin classes, including credential, launcher, template, retention, and machine-step logic. It allows authenticated Jenkins users with Overall/Read to trigger outbound HTTP requests to attacker-specified URLs using attacker-specified Jenkins credential IDs, potentially disclosing those credentials.
Likely exposure
Exposure is limited to Jenkins instances running Openstack Cloud Plugin 2.35 or earlier, especially where broad Overall/Read access exists and valuable cloud or deployment credentials are stored in Jenkins.
Exploitation context
The source bundle does not cite active exploitation or CISA KEV listing. Abuse requires Jenkins Overall/Read access and credential IDs obtained through another method, but successful exploitation could expose sensitive Jenkins-managed credentials.
Researcher notes
Evidence supports credential disclosure and attacker-controlled outbound HTTP requests in Openstack Cloud Plugin 2.35 and earlier. The bundle does not provide CVSS, CWE, exploit evidence, or exact fixed version details, so remediation should be anchored to Jenkins SECURITY-808.
Mitigation direction
- Identify Jenkins instances using Openstack Cloud Plugin 2.35 or earlier.
- Check Jenkins advisory SECURITY-808 for the vendor-supported fixed version or mitigation.
- Upgrade the plugin according to Jenkins guidance.
- Review and restrict Jenkins Overall/Read permissions.
- Rotate credentials that may have been exposed through affected Jenkins instances.
Validation and detection
- Inventory installed Jenkins plugins and confirm the Openstack Cloud Plugin version.
- Review Jenkins permission assignments for users with Overall/Read access.
- Audit Jenkins credentials referenced by Openstack Cloud Plugin jobs or templates.
- Check logs for unexpected outbound requests from Jenkins to unfamiliar URLs.
- Confirm remediation against the Jenkins SECURITY-808 advisory.
