WordPress Hide My WP plugin (versions <= 6.2.3) can be deactivated by any unauthenticated user. It is possible to retrieve a reset token which can then be used to deactivate the plugin.

The SQL injection vulnerability in the Hide My WP WordPress plugin (versions <= 6.2.3) is possible because of how the IP address is retrieved and used inside a SQL query. The function "hmwpgetuserip" tries to retrieve the IP address from multiple headers, including IP address headers that the user can spoof, such as "X-Forwarded-For." As a result, the malicious payload supplied in one of these IP address headers will be directly inserted into the SQL query, making SQL injection possible.

The Hide My WP WordPress plugin before 6.2.9 does not properly sanitize and escape a parameter before using it in a SQL statement via an AJAX action available to unauthenticated users, leading to a SQL injection.
