The pandemic has dramatically impacted the status of vulnerabilities for all of the major content management systems, like Joomla, Magento, and WordPress.
Hackers stuck at home with nothing to do but “code” have been wreaking havoc on the community of website management scripts, especially WordPress.
Luckily plugin and theme developers have likewise been “available” and most of the exploits listed below have patches in place now.
Sadly, the patches came too late for many. There has been a steady increase in privilege escalation hacks (where hackers gain access to lower-level user roles such as “Subscriber” to do their evil deeds).
Suffice it to say there is enough evidence to demonstrate that allowing subscribers to subscribe without any management oversight and not doing a reasonable amount of due diligence before installing a new plugin is a long term receipt for disaster.
Below is a shortlist of WordPress related plugins and theme whose code have been exploited in some way during the month of May (list credit to the WPScan Team).
