      <title>CVE-2026-12853 — Flamingo &lt;= 2.6.2 - Authenticated (Contributor+) Missing Authorization to Unauthorized Tag Information Disclosure via w…</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-12853</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; rocklobsterinc Flamingo&lt;/p&gt;
&lt;p&gt;The Flamingo plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.6.2. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with contributor-level access and above, to enumerate taxonomy terms including channel names derived from Contact Form 7 form titles that may reveal internal form purposes, department names, or workflow identifiers, as well as submission counts per channel and contact tag names. The plugin&amp;#39;s flamingo_map_meta_cap() filter restricts access to Flamingo&amp;#39;s admin UI but does not extend to WordPress core APIs such as XML-RPC wp.getTerms and admin-ajax ajax-tag-search.&lt;/p&gt;</description>
