SourceCVE-2023-23737

The popular WordPress plugin MainWP MainWP Broken Links Checker Extension, used for monitoring broken links on websites, is affected by a serious SQL injection vulnerability. SQL injection (SQLi) attacks work by inserting malicious SQL code into vulnerable web inputs that get executed by the backend database, compromising confidential data or taking control of the system.

In this case, unauthenticated attackers could exploit the vulnerability to execute arbitrary SQL commands on websites using the affected plugin versions, allowing them to view, modify or delete database content like user details. This puts sensitive user information at risk of theft or misuse.

If you are using one of the vulnerable versions of the MainWP Broken Links Checker Extension plugin, you should immediately update to the latest version to patch the security hole. Website owners should also regularly check their plugins and themes for updates to stay protected from newly discovered vulnerabilities. Proper user privileges on databases can further reduce risks from SQLi flaws.

It is also advisable to use a web application firewall or monitor logs for any anomalous SQL queries to detect potential attacks. Keeping software updated is one of the best ways to enhance the security of your WordPress site against exploits.
