CVE-2026-13392 ElementsKit CVE debrief

Who should care

Administrators of WordPress installations with the ElementsKit Elementor Addons plugin, especially those with multisite networks, should be aware of this vulnerability and take steps to mitigate it. They should prioritize updating to version 3.10.01 or later and restrict administrative capabilities to trusted users. Additionally, they should monitor server logs for suspicious activity and review compensating controls for exposed systems while remediation is scheduled and verified. Security teams and vulnerability management teams should also be aware of this vulnerability and track exceptions and retest remediated assets.

Technical summary

The ElementsKit Elementor Addons WordPress plugin before version 3.10.01 does not prevent a custom-widget definition saved by a user with administrative capabilities from being written verbatim into a generated PHP file that the plugin subsequently executes, allowing arbitrary PHP code to run on the server. This vulnerability can be exploited by a non-super subsite Administrator on a multisite network, allowing them to achieve host-level code execution beyond the privileges the network grants them. The vulnerability has a CVSS score of 7.2 and a severity of HIGH.
