Unauthorized deployments via artifact-controlled signature policy
Published Sep 11, 2026 · Updated Sep 14, 2026
Trust-policy bypass in Doco-CD before 0.90.1 allows remote authenticated users to deploy attacker-controlled OCI content. Artifact-supplied .doco-cd.yml data is trusted to set oci.verify false, allowing the artifact to disable the global signature policy used to verify itself. Exploitation requires write access to a configured OCI tag, global verification enabled, and an artifact-sourced deployment flow; successful use applies untrusted Compose configuration and can disrupt managed services.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
