Prior to version 7.4.0, an authenticated administrator can achieve Remote Code Execution (RCE) on the server by installing a malicious plugin ZIP archive containing a PHP webshell. The application explicitly includes &#8216;php&#8217; in its ALLOWED_EXTENSIONS list, while the dangerous extensions denylist (DENIED_EXTENSIONS) fails to block standard .php files. Because `php` is explicitly included in the allowed extension list for plugin archives, and extracted files are placed directly under the web root, any PHP file inside the ZIP becomes immediately executable via HTTP \u2014 without even needing to &#8220;enable&#8221; the plugin through the application UI. The \/plugins\/install-url API route (management.php) allows an administrator to source the malicious ZIP from any attacker-controlled HTTPS URL, validating it only against an attacker-supplied SHA-256 hash. This issue has been fixed in version 7.4.0.<\/p>\n<p>  Severity: 9.1 | CRITICAL<\/p>\n<p>  Visit the link for more details, such as CVSS details, affected products, timeline, and more&#8230;\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CVE ID :CVE-2026-58409 Published : July 13, 2026, 9:16 p.m. | 13\u00a0minutes ago Description :ChurchCRM is an open-source church management system.
