CVE-2026-14230
MediumCVSS 5.4Exploitation Probability (EPSS)
Low risk3th percentile - higher than 3% of all known CVEs
Summary
The ECS WordPress plugin before version 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). 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.
Risk Assessment
Risk of malicious script execution in the browsers of administrators and visitors, potentially leading to session theft, account takeover, or malware distribution.
Recommendation
Immediately update the ECS plugin to version 4.3.8 or later and restrict Contributor role permissions if possible.
Original NVD description (English source)
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.
