What the vulnerability does
The GB Forms DB plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 1.0.2 via the gbfdb_talk_to_front() function. This is due to the function accepting user input and then passing that through call_user_func(). This makes it possible for unauthenticated attackers to execute code on the server which can be leverage to inject backdoors or create new administrative user accounts to name a few things.
Explanation of Vulnerability in Simple Terms
GB Forms DB versions 1.0.2 and earlier contain a code injection vulnerability that allows unauthenticated attackers to run arbitrary PHP code on the site without user interaction. The vulnerability stems from improper handling of user input, enabling direct code execution. All versions up to 1.0.2 are affected.
What an attacker can do
Run arbitrary PHP code on the site and take complete control of it.
Potential impact on your site
Complete compromise of the site, including data theft, malware installation, and defacement.
