CVE-2024-47803: Jenkins exposes multi-line secrets through error messages

October 2, 2024

Jenkins

Jenkins provides the secretTextarea form field for multi-line secrets.

Jenkins 2.478 and earlier, LTS 2.462.2 and earlier does not redact multi-line secret values in error messages generated for form submissions involving the secretTextarea form field.

This can result in exposure of multi-line secrets through those error messages, e.g., in the system log.

Jenkins 2.479, LTS 2.462.3 redacts multi-line secret values in error messages generated for form submissions involving the secretTextarea form field.
