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 Track The Click WordPress plugin before 0.3.12 does not properly sanitize query parameters to the stats REST endpoint before using them in a database query, allowing a logged in user with an author role or higher to perform time based blind SQLi attacks on the database.
