CVE-2026-27503: Radioinorr Svxportal

Medium severity, CVSS 6.1. EPSS: 0.3% chance of exploitation in the next 30 days.

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.
