CVE-2020-2118Network attack vector

Credential ID disclosure via unchecked form enumeration

Published Feb 12, 2020 · Updated Aug 4, 2024

Information disclosure in Jenkins Pipeline GitHub Notify Step 1.0.4 and earlier allows remote authenticated users to enumerate credential IDs. The doFillCredentialsIdItems form method returns applicable credential IDs without first enforcing Item/Configure permission. Overall/Read access is sufficient; the exposed IDs do not reveal secret values directly but can support a separate credential-capture flaw.
