Vulnerability Title
WP Recipe Maker <= 10.3.2 - Insecure Direct Object Reference to Unauthenticated Arbitrary Post Metadata Modification via 'recipeId' Parameter
Source: CVE Program / CVE List V5
Vulnerability Description
The WP Recipe Maker plugin for WordPress is vulnerable to an Insecure Direct Object Reference (IDOR) in versions up to, and including, 10.3.2. This is due to the /wp-json/wp-recipe-maker/v1/integrations/instacart REST API endpoint's permission_callback being set to __return_true and a lack of subsequent authorization or ownership checks on the user-supplied recipeId. This makes it possible for unauthenticated attackers to overwrite arbitrary post metadata (wprm_instacart_combinations) for any post ID on the site via the recipeId parameter.
