XSS in Radioinorr Svxportal
CVE-2026-27504
SVXportal version 2.5 and prior contain a reflected cross-site scripting vulnerability in radiomobile_front.php via the stationid query parameter. When an authenticated administrator views a crafted URL, the application embeds the unsanitized parameter value into a hidden input value field, allowing attacker-supplied script injection and execution in the administrator's browser. This can be used to compromise admin sessions or perform unauthorized actions via the administrator's authenticated context.
