The Cooked Pro WordPress plugin before 1.7.5.7 does not properly validate or sanitize the recipe_args parameter before unserializing it in the cooked_loadmore action, allowing an unauthenticated attacker to trigger a PHP Object injection vulnerability.
The Cooked Pro WordPress plugin before 1.7.5.6 was affected by unauthenticated reflected Cross-Site Scripting issues, due to improper sanitisation of user input while being output back in pages as an arbitrary attribute.
