Attack profile from CVSS 3.1 · CISA ADP. Fix status from CNA. Impact type from CWE-352.

Summary

The Newsletters WordPress plugin before 4.17 does not perform any nonce or capability check when saving one of its settings screens, and writes every submitted parameter into its own options, allowing attackers to make a logged in administrator overwrite arbitrary Newsletters WordPress plugin before 4.17 settings, including the credential protecting its API, via a Cross-Site Request Forgery attack.
