CVE-2022-20620Network attack vector

Credential ID disclosure via unchecked HTTP endpoints

Published Jan 12, 2022 · Updated Aug 3, 2024

Missing authorization in Jenkins SSH Agent Plugin 1.23 and earlier allows remote authenticated users to enumerate stored credential IDs. Several HTTP endpoints return credential-selection data without first enforcing the permissions required to view the referenced credentials. Overall/Read access is sufficient; the identifiers do not disclose secret values directly but can support credential capture through a separate flaw.
