AI Powered Q&A
Can you explain this vulnerability to me?
The Avada (Fusion) Builder plugin for WordPress has a vulnerability in versions up to and including 3.15.1. The issue arises because the plugin's function `fusion_get_post_custom_field()` does not properly check if metadata keys are protected (those starting with an underscore). As a result, authenticated users with Subscriber-level access or higher can access protected post metadata fields that should normally be hidden, using the Dynamic Data feature's `post_custom_field` parameter.
How can this vulnerability impact me? :
This vulnerability allows attackers with low-level authenticated access to extract sensitive or protected metadata from posts that should not be publicly accessible. This could lead to exposure of confidential or private information stored in these metadata fields, potentially compromising the privacy or security of the website's content or users.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
This vulnerability allows authenticated users with Subscriber-level access and above to extract protected post metadata fields that should not be publicly accessible. Such unauthorized exposure of sensitive information could potentially lead to non-compliance with data protection regulations like GDPR and HIPAA, which require safeguarding personal and sensitive data from unauthorized access.
