      <title>CVE-2026-4124 — Ziggeo &lt;= 3.1.1 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Modification via 'ziggeo_ajax' AJAX Ac…</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2026-4124</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; oliverfriedmann Ziggeo&lt;/p&gt;
&lt;p&gt;The Ziggeo plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 3.1.1. The wp_ajax_ziggeo_ajax handler  only verifies a nonce (check_ajax_referer) but performs no capability checks via current_user_can(). Furthermore, the nonce (&amp;#39;ziggeo_ajax_nonce&amp;#39;) is exposed to all logged-in users on every page via the wp_head and admin_head hooks . This makes it possible for authenticated attackers, with Subscriber-level access and above, to invoke multiple administrative operations including: saving arbitrary translation strings (translations_panel_save_strings via update_option(&amp;#39;ziggeo_translations&amp;#39;)), creating/updating/deleting event templates (event_editor_save_template/update_template/remove_template via update_option(&amp;#39;ziggeo_events&amp;#39;)), modifying SDK application settings (sdk_applications operations), and managing notifications (notification_handler via update_option(&amp;#39;ziggeo_notifications&amp;#39;)).&lt;/p&gt;</description>
