CVE-2026-14752Public exploitNetwork attack vector

Stored XSS via unencoded dictionary reference

Published Jul 5, 2026 · Updated Jul 5, 2026

Stored cross-site scripting in mjperpinosa stumasy allows remote authenticated users to execute JavaScript in other users' browsers. The add_definition path stores the reference parameter unchanged, and display_dictionary.php concatenates it into HTML before notes.js inserts the response with jQuery .html(). A valid account is required to store the payload, and execution occurs when another user views the affected dictionary word.
