## What is CVE-2026-23722?

CVE-2026-23722 is a critical cross-site scripting vulnerability in Wegia Wegia, published on 16 Jan 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

WeGIA is a Web Manager for Charitable Institutions. Prior to 3.6.2, a Reflected Cross-Site Scripting (XSS) vulnerability was discovered in the WeGIA system, specifically within the html/memorando/insere_despacho.php file. The application fails to properly sanitize or encode user-supplied input via the id_memorando GET parameter before reflecting it into the HTML source (likely inside a <script> block or an attribute). This allows unauthenticated attackers to inject arbitrary JavaScript or HTML into the context of the user's browser session. This vulnerability is fixed in 3.6.2.

Weakness: CWE-79 (Improper Neutralization of Input During Web Page Generation)
