CVE-2024-13521: Ilghera Mailup Auto Subscription

Medium severity, CVSS 5.4. EPSS: 0.1% chance of exploitation in the next 30 days.

The MailUp Auto Subscription plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.1.0. This is due to missing or incorrect nonce validation on the mas_options function. This makes it possible for unauthenticated attackers to update settings and inject malicious web scripts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
