This is an interesting Python script that attempts to check for known SQL injection vulnerabilities in a given WordPress installation. The script takes in a website URL as input and can also take a proxy address as an optional parameter. It then uses a list of SQL injection payloads to check for vulnerabilities on the target website. If a vulnerability is found, the script reports it to the user.
It's worth noting that the use of this script is potentially dangerous, as it could be used for malicious purposes. Additionally, websites should be tested for vulnerabilities with the owner's permission.
