Jenkins Email Extension Plugin SMTP password transmitted and displayed in plain text

  • Disclosed: 24.05.2022
  • Updated: 11.10.2026 11:22

Email Extension Plugin stores an SMTP password in its global configuration file hudson.plugins.emailext.ExtendedEmailPublisher.xml on the Jenkins controller as part of its configuration.

While this password is stored encrypted on disk, it is transmitted and displayed in plain text as part of the configuration form by Email Extension Plugin 2.72 and 2.73. This can result in exposure of the password.

Email Extension Plugin 2.74 transmits the SMTP password in its global configuration encrypted and masks it using a password field.
