AI Powered Q&A
Can you explain this vulnerability to me?
The WP Recipe Maker plugin for WordPress has a vulnerability known as Insecure Direct Object Reference (IDOR) in versions up to and including 10.3.2. This vulnerability exists because the REST API endpoint /wp-json/wp-recipe-maker/v1/integrations/instacart has its permission callback set to always allow access (__return_true) without proper authorization or ownership checks on the user-supplied recipeId parameter.
As a result, unauthenticated attackers can exploit this flaw to overwrite arbitrary post metadata (specifically wprm_instacart_combinations) for any post ID on the affected WordPress site.
How can this vulnerability impact me? :
This vulnerability allows unauthenticated attackers to modify post metadata on the affected WordPress site without permission. While it does not directly impact confidentiality or availability, it can lead to integrity issues by allowing attackers to overwrite data associated with posts.
Such unauthorized modifications could disrupt the normal functioning of the site, potentially causing incorrect or malicious content to be displayed or processed.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
