WPScan Vulnerability Database Falsely Claims WP Job Manager Contained Arbitrary File Upload Vulnerability

When it comes to getting data on vulnerabilities in WordPress plugins there are a number of companies that are interested in making it appear they are generating that type of data without having to do the work it takes to provide that. They instead of reuse data from the WPScan Vulnerability Database, sometimes without disclosing that is the source and in every instance we have seen so far, without providing a warning as the low quality of the data.

In other cases the change duplicates something already occurring in the plugin or WordPress, which increases resource usage slightly, but doesn’t really make a major change. But as what happened recently with WP Job Manager shows it is possible that it could have a negative impact.
