Sep 25, 2026SSL Zen — SSL Certificate Installer & HTTPS Redirects: Directory TraversalCVE-2026-17602 · affects up to 4.7.42 · reported by WordfenceMedium 4.9
The SSL Zen — SSL Certificate Installer & HTTPS Redirects plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 4.7.42 via the 'file_name' parameter parameter. This makes it possible for authenticated attackers, with administrator-level access and above, to read the contents of arbitrary files on the server, which can contain sensitive information.

Sep 25, 2026SSL Zen: Reflected Cross-Site ScriptingCVE-2026-17577 · affects up to 4.7.42 · reported by WordfenceMedium 6.1
The SSL Zen plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'uri' (and 'host') parameters in versions up to, and including, 4.7.42. The ssl_zen_messages::getMessages() function builds the 'token_missmatch' message using base64_decode(sanitize_text_field($_REQUEST['uri'])) and (optionally) base64_decode(sanitize_text_field($_REQUEST['host'])). sanitize_text_field() cannot strip HTML/JavaScript that is hidden inside a base64-encoded blob, and the resulting decoded raw HTML is echoed unescaped by showMessage() . 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 specially crafted link.

May 8, 2024SSL Zen: Does not properly prevent directory listing of the private keys folderCVE-2024-1076 · fixed in 4.6.0 · reported by WPScanMedium 6.5
The SSL Zen WordPress plugin before 4.6.0 does not properly prevent directory listing of the private keys folder, as it only relies on the use of .htaccess to prevent visitors from accessing the site's generated private keys, which allows an attacker to read them if the site runs on a server who doesn't support .htaccess files, like NGINX.
