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.
AnalysisAI
Unauthenticated attackers can modify arbitrary post metadata in WordPress sites running WP Recipe Maker plugin versions up to 10.3.2 due to an insecure direct object reference in the Instacart integration REST API endpoint. The vulnerability stems from improper authorization checks on the recipeId parameter, allowing attackers to overwrite recipe configuration data without authentication. No patch is currently available for this issue.
