The Freemius SDK, as used by hundreds of WordPress plugin and theme developers, was vulnerable to Cross-Site Request Forgery and Information disclosure due to missing capability checks and nonce protection on the _get_debug_log, _get_db_option, and the _set_db_option functions in versions up to, and including 2.4.2. Any WordPress plugin or theme running a version of Freemius less than 2.4.3 is vulnerable.

The Edit Comments XT WordPress plugin is vulnerable to Reflected Cross-Site Scripting due to a reflected $_SERVER["PHP_SELF"] value in the ~/edit-comments-xt.php file which allows attackers to inject arbitrary web scripts, in versions up to and including 1.0.

The Edit Comments WordPress plugin through 0.3 does not sanitise, validate or escape the jal_edit_comments GET parameter before using it in a SQL statement, leading to a SQL injection issue
