Email Subscribers & Newsletters – Email Marketing, Post Notifications & Newsletter Plugin for WordPress < 5.9.34 - Unauthenticated Stored Cross-Site Scripting

Description

The Email Subscribers & Newsletters – Email Marketing, Post Notifications & Newsletter Plugin for WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 5.9.33. This is due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
