What is CVE-2026-13392?
CVE-2026-13392 is a high-severity code injection vulnerability in Unknown ElementsKit Elementor Addons, published on 31 Jul 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Official description
The ElementsKit Elementor Addons WordPress plugin before 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 ElementsKit Elementor Addons WordPress plugin before 3.10.01 subsequently executes, allowing arbitrary PHP code to run on the server; on a multisite network this lets a non-super subsite Administrator, who is otherwise denied code/file editing, reach host-level code execution beyond the privileges the network grants them.
Weakness: CWE-94
