OpenSTAManager is an open source management software for technical assistance and invoicing. OpenSTAManager v2.9.8 and earlier contains Reflected XSS vulnerabilities in invoice/order/contract modification modals. The application fails to properly sanitize user-supplied input from the righe GET parameter before reflecting it in HTML output.The $_GET['righe'] parameter is directly echoed into the HTML value attribute without any sanitization using htmlspecialchars() or equivalent functions. This allows an attacker to break out of the attribute context and inject arbitrary HTML/JavaScript.

GHSA-jfgp-g7x7-j25j — OpenSTAManager Affected by XSS in modifica_iva.php via righe parameter

Affected: Packagist: devcode-it/openstamanager

### Summary

Multiple Reflected Cross-Site Scripting (XSS) vulnerabilities in OpenSTAManager v2.9.8 allow unauthenticated attackers to execute arbitrary JavaScript code in the context of other users' browsers through crafted URL parameters, potentially leading to session hijacking, credential theft, and unauthorized actions.

**Vulnerable Parameter:** `righe` (GET)

### Details

OpenSTAManager v2.9.8 contains multiple Reflected XSS vulnerabilities in invoice/order/contract modification modals. The application fails to properly sanitize user-supplied input from the `righe` GET parameter before reflecting it in HTML output.

**Vulnerable Code Location:** File: `/modules/contratti/modals/modifica_iva.php` (Line 125)

```php <input type="hidden" name="righe" value="<?php echo $_GET['righe']; ?>"> ```
