When Jenkins fails to process form submissions due to an internal error, the error message shown to the user and written to the log typically includes the serialized JSON form submission. Secrets, such as submitted passwords, might be included with the JSON object, and shown or written to disk in plain text.

Jenkins security policy[0]: "Any security advisory related updates to Jenkins core or the plugins we include in the OpenShift Jenkins master image will only occur in the v3.11 and v4.x branches of this repository. We do support running the v3.11 version of the master image against older v3.x (as far back as v3.4) OpenShift clusters if you want to pick up Jenkins security advisory updates."
