Technical details
The vulnerability is a stored DOM XSS in the memorandum dispatch feature: the `texto` field is sanitized during storage using `FILTER_SANITIZE_SPECIAL_CHARS` but then decoded with `html_entity_decode()` and inserted via jQuery `.html()`, which treats the string as HTML. An authenticated attacker can submit a dispatch via `/controle/control.php` with crafted JavaScript, which persists and executes client-side when any user views the thread. This allows theft of PHPSESSID cookies and privilege escalation.
