CyberRota Analysis
AI-GeneratedThe MailChimp Forms by MailMunch plugin for WordPress is vulnerable due to a lack of capability checks in the `sign_in()` and `sign_up()` AJAX handlers, allowing authenticated attackers with Subscriber-level access or higher to compromise the integration with MailMunch. This vulnerability enables attackers to redirect subscriber data to their own MailMunch account, potentially leading to data theft and unauthorized control over forms and landing pages. WordPress site administrators using this plugin should prioritize patching to mitigate the risk of data breaches and unauthorized access.
Original NVD Description
The MailChimp Forms by MailMunch plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the `sign_in()` and `sign_up()` AJAX handlers in all versions up to, and including, 3.2.7. This makes it possible for authenticated attackers, with Subscriber-level access and above, to relink the site's MailMunch integration to an attacker-controlled MailMunch account by submitting attacker-supplied credentials. Once relinked, all subscriber data captured by the plugin's forms is delivered to the attacker, and the forms/landing pages rendered on the site are pulled from the attacker's MailMunch account.
