      <title>CVE-2026-8886 — hk_shortcode &lt;= 1.0 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'title' Shortcode Attribute</title>
      <link>https://db.gcve.eu/vuln/cve-2026-8886</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; huankong hk_shortcode&lt;/p&gt;
&lt;p&gt;The hk_shortcode plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the &amp;#39;title-plane&amp;#39; shortcode in versions up to, and including, 1.0. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes in the huankong_post_short_title_plane() function, where the &amp;#39;title&amp;#39; attribute is concatenated directly into HTML output without any escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.&lt;/p&gt;</description>
