Summary
The InstaWP Connect plugin for WordPress is vulnerable to unauthorized access of data, modification of data, and loss of data due to a missing capability check on the 'events_receiver' function in versions up to and including 0.0.9.18. This allows unauthenticated attackers to add, modify, or delete posts and taxonomies, install, activate, or deactivate plugins, change customizer settings, and manage users, including administrator users.
Risk Assessment
The lack of proper security checks in the plugin poses a serious risk to data integrity and system security, allowing attackers full control over the site.
Recommendation
It is recommended to update the plugin to the latest version that includes security fixes and to conduct an audit of user permissions in the system.
