Security readout for executives and security teams
Plain-English summary
Jenkins DotCi Plugin 2.40.00 and earlier can process YAML in a way that may create arbitrary Java object types, leading to remote code execution. For affected Jenkins environments, this is business-critical because compromise could expose build secrets, source code, deployment credentials, and CI/CD integrity.
Executive priority
Treat as urgent for any Jenkins environment using DotCi Plugin. CI/CD compromise can become a route to source code, secrets, and production deployment systems. If the plugin is absent, priority drops substantially.
Technical view
The issue is unsafe deserialization/class instantiation in YAML parsing, mapped to CWE-502. The CVSS 3.1 score is 9.8 with network access, low complexity, no privileges, and no user interaction, with high confidentiality, integrity, and availability impact.
Likely exposure
Exposure is limited to Jenkins deployments running the DotCi Plugin version 2.40.00 or earlier. The source bundle does not confirm default installation, internet exposure, or affected configuration paths.
Exploitation context
The CVSS vector indicates remote unauthenticated exploitability without user interaction. The provided data does not show CISA KEV listing or cited evidence of active exploitation, so active exploitation should not be asserted.
Researcher notes
Evidence supports a YAML parser configuration flaw enabling arbitrary type instantiation and RCE. The bundle does not include a fixed version, exploit proof, affected endpoints, or vendor mitigation details beyond the Jenkins advisory reference.
Mitigation direction
- Inventory Jenkins controllers for the DotCi Plugin and its version.
- Check Jenkins advisory and plugin guidance for fixed-version or removal instructions.
- Prioritize affected Jenkins systems that are internet-facing or handle deployment secrets.
- Restrict Jenkins access while remediation guidance is being confirmed.
- Review CI/CD credentials and secrets if compromise is suspected.
Validation and detection
- Confirm whether DotCi Plugin is installed on each Jenkins controller.
- Verify installed plugin versions are not 2.40.00 or earlier.
- Review Jenkins logs for unexpected DotCi job activity or plugin errors.
- Confirm Jenkins exposure boundaries, including VPN, SSO, and public access.
- Document compensating controls if vendor remediation is unavailable.

Deserialization of Untrusted Data
Deserialization of Untrusted Data represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
