CVE-2025-64148Network attack vector

Credential ID disclosure via unchecked form validation

Published Oct 29, 2025 · Updated Oct 29, 2025

Missing authorization in Jenkins Publish to Bitbucket Plugin 0.4 and earlier allows remote authenticated users to enumerate credential IDs. A form-validation method returns identifiers for credentials stored in Jenkins without checking whether the caller has permission to view them. Overall/Read permission is sufficient; the identifiers do not reveal secret values directly but can support credential capture when chained with another flaw.
