Does this matter?

Lower severity and a low EPSS score (0.15%). Track it; it rarely justifies an emergency change on its own.

Description

SVXportal version 2.5 and prior contain a reflected cross-site scripting vulnerability in admin/log.php via the search query parameter. When an authenticated administrator views a crafted URL, the application embeds the unsanitized parameter value directly into an HTML input value attribute, allowing attacker-supplied JavaScript to execute in the administrator's browser. This can enable session theft, administrative action forgery, or other browser-based compromise in the context of an admin user.
