      <title>CVE-2026-78159 — The Events Calendar &lt;= 6.17.3 - Unauthenticated Code Injection to Remote Code Execution via Widget 'classes' Map Callab…</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-78159</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; stellarwp The Events Calendar&lt;/p&gt;
&lt;p&gt;The The Events Calendar plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 6.17.3 via the parse_array function. This is due to insufficient validation of the widget &amp;#39;classes&amp;#39; map, allowing a plain-array payload to bypass the is_safe_widget_instance() object check and reach the callable-invocation sink in Element_Classes::parse_array(). This makes it possible for unauthenticated attackers to execute code on the server. Exploitation requires that the targeted site has comments enabled on tribe_events posts and that at least one comment containing a crafted wp:legacy-widget block has been submitted, as the attack chain is triggered when do_blocks() processes the single-event HTML including the comment area.&lt;/p&gt;</description>
