AI Powered Q&A
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
The vulnerability allows authenticated users with Subscriber-level access to modify arbitrary string-based user meta keys for their own account due to a missing capability check. This unauthorized modification of user data could potentially lead to non-compliance with data protection regulations such as GDPR or HIPAA, which require strict controls over personal data integrity and access. However, specific impacts on compliance are not detailed in the provided resources.
Can you explain this vulnerability to me?
This vulnerability exists in the All-in-One Video Gallery WordPress plugin versions 4.1.0 to 4.6.4. It is caused by a missing capability check in the ajax_callback_store_user_meta() function, which allows authenticated users with Subscriber-level access or higher to modify arbitrary string-based user meta keys for their own account without proper authorization.
How can this vulnerability impact me? :
The vulnerability allows authenticated users with low-level access (Subscriber and above) to update arbitrary user meta data for their own account. This could lead to unauthorized changes in user metadata, potentially affecting user profile information or plugin behavior tied to user meta, which may result in data integrity issues or unexpected plugin behavior.
What immediate steps should I take to mitigate this vulnerability?
To mitigate this vulnerability, immediately update the All-in-One Video Gallery WordPress plugin to a version later than 4.6.4 where the missing capability check on the ajax_callback_store_user_meta() function is fixed. Additionally, review user roles and permissions to ensure that Subscriber-level users do not have unnecessary capabilities. Consider applying any available patches or fixes provided by the plugin maintainers and monitor for plugin updates that address this issue.
