CVE-2026-18788Public exploitNetwork attack vector

Trusted-origin content injection via anonymous file creation

Published Aug 4, 2026 · Updated Aug 4, 2026

Unrestricted file creation in Trippo Responsive FileManager 9.14.0 allows remote attackers to publish HTML or JavaScript files. dialog.php initializes a trusted session without an access key, and execute.php accepts create_file requests that write attacker-controlled text into the public source directory. The default configuration disables access-key enforcement and permits HTML and JavaScript creation, enabling stored script execution or attacker-controlled content under the site's origin.
