What is CVE-2021-4341?

The uListing plugin for WordPress has a vulnerability that allows for an authorization bypass via AJAX. This is caused by inadequate capability checks, lack of input validation, and absence of a security nonce in the stm_update_email_data AJAX action. As a result, unauthenticated attackers can alter any WordPress option stored in the database, posing a significant security threat to WordPress installations using this plugin.
