Input validation vulnerability in RESTful Content Syndication 1.5.0

The RESTful Content Syndication plugin for WordPress has a security vulnerability that could allow attackers to upload any type of file to a website using the plugin. This could potentially lead to remote code execution, but only if the attacker has Author-level access or higher. This vulnerability is more likely to be exploited by administrators who can also access the plugin’s settings, rather than contributor-level users.
