CVE-2026-8628
Description
The EntreDroppers plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via PHP_SELF Parameter in all versions up to, and including, 1.1.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. The payload is delivered via attacker-controlled path-info in the URL (e.g., /wp-admin/admin.php/"><script>alert(0)</script>/?page=EntreDroppers.php), which PHP_SELF reflects directly into the form action attribute.
Summary dbcve.org
The EntreDroppers WordPress plugin fails to sanitize the PHP_SELF server variable before reflecting it into HTML form action attributes. An unauthenticated attacker can craft malicious URLs containing script tags in the path-info portion (e.g., /wp-admin/admin.php/\"><script>alert(0)</script>/) that execute when victim users click specially crafted links.
Mitigation
Upgrade to version 1.1.3 or later which contains the patch; alternatively, disable the plugin until a fix is available. The fix requires sanitizing PHP_SELF using sanitize_text_field() or similar and escaping output with esc_attr() before rendering in HTML attributes.
