Multiple WordPress Plugins SQL Injection Vulnerabilities

In July 2019, I discovered and reported nine SQL injection vulnerabilities in nine different popular WordPress plugins across a variety of categories, including advertisement, donation, gallery, forms, newsletter, and video player. These plugins are being actively used by hundreds of thousands of WordPress websites, with some of them ranked in the top position for their corresponding category.

An interesting point is eight out of nine vulnerabilities were found with the same simple code pattern that made them vulnerable to a SQL injection. In spite of the potential for exploit, many developers simply do not carefully filter user-supplied data. And in this case, this happened despite WordPress Core’s efforts, since they support various built-in methods to ensure that any user-supplied data is well-sanitized.
