What the vulnerability does
01Description
The weMail - Email Marketing, Lead Generation, Optin Forms, Email Newsletters, A/B Testing, and Automation plugin for WordPress is vulnerable to unauthorized form deletion in all versions up to, and including, 2.0.7. This is due to the `Forms::permission()` callback only validating the `X-WP-Nonce` header without checking user capabilities. Since the REST nonce is exposed to unauthenticated visitors via the `weMail` JavaScript object on pages with weMail forms, any unauthenticated user can permanently delete all weMail forms by extracting the nonce from the page source and sending a DELETE request to the forms endpoint.
Explanation of Vulnerability in Simple Terms

weMail versions up to 2.0.7 lack proper authorization checks, allowing unauthenticated attackers to modify data and disrupt service. The vulnerability affects the email marketing plugin for WooCommerce without requiring user interaction. Site administrators should update immediately to a version newer than 2.0.7.
