{"cve":"CVE-2026-2918","nvd":{"published":"2026-03-11T08:16:03.567","modified":"2026-06-17T10:32:02.017","status":"Deferred","description":"The Happy Addons for Elementor plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.21.0 via the `ha_condition_update` AJAX action. This is due to the `validate_reqeust()` method using `current_user_can('edit_posts', $template_id)` instead of `current_user_can('edit_post', $template_id)` — failing to perform object-level authorization. Additionally, the `ha_get_current_condition` AJAX action lacks a capability check. This makes it possible for authenticated attackers, with Contributor-level access and above, to modify the display conditions of any published `ha_library` template. Because the `cond_to_html()` renderer outputs condition values into HTML attributes without proper escaping (using string concatenation instead of `esc_attr()`), an attacker can inject event handler attributes (e.g., `onmouseover`) that execute JavaScript when an administrator views the Template Conditions panel, resulting in Stored Cross-Site Scripting.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","score":6.4},"cwes":["CWE-639"],"references":["https://plugins.trac.wordpress.org/browser/happy-elementor-addons/tags/3.20.7/classes/condition-manager.php#L237","https://plugins.trac.wordpress.org/browser/happy-elementor-addons/tags/3.20.7/classes/condition-manager.php#L525","https://plugins.trac.wordpress.org/browser/happy-elementor-addons/trunk/classes/condition-manager.php#L237","https://plugins.trac.wordpress.org/browser/happy-elementor-addons/trunk/classes/condition-manager.php#L525","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&new=3475242%40happy-elementor-addons%2Ftrunk&old=3463375%40happy-elementor-addons%2Ftrunk&sfp_email=&sfph_mail="],"products":[],"source":"nvd","synced_at":"2026-10-19T22:25:53.701907451+00:00"},"epss":{"cve":"CVE-2026-2918","score":0.00201,"percentile":0.10012,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
