The WP Mail Log plugin for WordPress is vulnerable to Stored Cross-Site Scripting via email contents in versions up to, and including, 1.1.1 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.
The AnyWhere Elementor WordPress plugin before 1.2.8 discloses a Freemius Secret Key which could be used by an attacker to purchase the pro subscription using test credit card numbers without actually paying the amount. Such key has been revoked.
