WordPress Plugin Vulnerabilities
Newsletters < 4.17 - Arbitrary Plugin Option Update via CSRF
Description
The plugin 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 plugin settings, including the credential protecting its API, via a Cross-Site Request Forgery attack.
