## 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 (Improper Control of Generation of Code)
