High severity, CVSS 8.8. EPSS: 8.2% chance of exploitation in the next 30 days.

In the Reponsive Menu (free and Pro) WordPress plugins before 4.0.4, subscribers could upload zip archives containing malicious PHP files that would get extracted to the /rmp-menu/ directory. These files could then be accessed via the front end of the site to trigger remote code execution and ultimately allow an attacker to execute commands to further infect a WordPress site.
