Input validation vulnerability in ADFO – Custom data in admin dashboard 1.9.1

The ADFO – Custom data plugin for WordPress has a security issue that allows hackers to inject harmful code into the system. This can only be done by an attacker who has high-level access and is authenticated. However, this vulnerability will not have an impact unless there is another plugin or theme installed on the site that also has a security issue. If this is the case, the attacker may be able to delete files, access private information, or run malicious code.
