      <title>CVE-2026-55212 — Pimcore: Insufficient Permission Check on Class Definition Creation Endpoint Allows Privilege Escalation</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-55212</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; pimcore&lt;/p&gt;
&lt;p&gt;Pimcore is an Open Source Data &amp;amp; Experience Management Platform. Prior to 2025.4.6 and 2026.1.6, the Studio API class definition creation endpoint POST /pimcore-studio/api/class/definition/configuration-view/detail/create is guarded by the objects permission instead of the classes permission, allowing a standard editor-level user to create class definitions without admin privileges. Class definition creation generates new database tables and PHP class files on the server, and missing API-layer UID format validation allows malformed UIDs to reach model-layer validation and return internal exceptions. This issue is fixed in versions 2025.4.6 and 2026.1.6.&lt;/p&gt;</description>
