Credential disclosure via unmasked npm credentials
Published Aug 16, 2023 · Updated Oct 8, 2024
Improper credential masking in Jenkins NodeJS Plugin 1.6.0 and earlier allows remote authenticated users to expose npm credentials in Pipeline build logs. The plugin's NPMConfig integration failed to provide registry usernames, passwords, tokens, and encoded HTTP-basic values to Jenkins's console log masking filter, so matching secrets were emitted in clear text. An authenticated user who can configure or run a Pipeline using an affected npm configuration can read the resulting build log; the issue discloses credentials but does not itself grant code execution or alter builds.

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.
