CVE-2026-40283Public exploitNetwork attack vector

Stored XSS via unescaped patient name

Published Apr 17, 2026 · Updated Apr 17, 2026

Stored XSS in WeGIA before 3.6.10 allows remote authenticated users to execute JavaScript when patient information is viewed. The Nome field in profile_paciente.php accepts patient names without sanitization or output encoding, and the page renders the stored value into the DOM without escaping. An account able to create or edit a patient can plant the payload; execution occurs in the browser of any user who later opens that patient's information.
