      <title>CVE-2026-55695 — FearlessCMS: Remote Code Execution via Unvalidated Update Repository URL in System Updater</title>
      <link>https://db.gcve.eu/vuln/cve-2026-55695</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; fearlessgeekmedia FearlessCMS&lt;/p&gt;
&lt;p&gt;FearlessCMS is a flat-file content management system centered on simplicity and open source. In 0.1.2b and earlier, an authenticated administrator can set an arbitrary Git repository URL through admin/updater-handler.php and trigger perform_update, which passes the URL to update.sh. The updater clones the repository and replaces the live plugins/, admin/, and includes/ directories without verifying the repository&amp;#39;s identity, signatures, or contents. Because router.php permits existing PHP files under plugins to be executed by the PHP development server, attacker-supplied update content can execute arbitrary PHP with the web server process&amp;#39;s privileges and persist as a backdoor. This issue is fixed in version 0.1.3b.&lt;/p&gt;</description>
