What is CVE-2026-14230?
CVE-2026-14230 is a medium-severity cross-site scripting vulnerability in Unknown ECS, published on 15 Aug 2026. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Official description
The ECS WordPress plugin before 4.3.8 does not perform capability or object-ownership checks on its Dynamic Repeater AJAX handlers (gated only by a capability-agnostic nonce that any edit_posts user obtains from the Elementor editor), so a Contributor can write a data-source binding into any post — including admin-authored pages — whose attacker-controlled values are rendered into a widget's repeater output without sanitization, executing JavaScript in the session of any visitor or administrator who views the page.
Weakness: CWE-79
