## How to fix

- Fixed in 3.8.7

## Technical details

The vulnerability is a stored cross-site scripting (XSS) flaw in the `saude/historico_prontuarios.php` file where the `textoProntuario` field fails to sanitize user input before rendering it with `innerHTML`. An authenticated attacker can submit malicious JavaScript via POST to `/controle/control.php` with parameters `nomeClasse=SaudeControle`, `metodo=alterarProntuario`, and `id_fichamedica`. The stored payload executes in victims' browsers when accessing the medical history page, enabling session cookie theft and privilege-dependent account takeover. The fix changes `innerHTML` to `textContent` to prevent script execution.
