WordPress Plugin Vulnerabilities
Newsletters < 4.17 - Unauthenticated API Access via Predictable API Key
Description
The plugin does not generate its API key using a sufficiently random source, deriving it from a publicly known value, allowing unauthenticated attackers to compute the key and perform privileged actions such as adding and deleting subscribers and sending emails, when the optional API has been enabled.
