CVE-2026-27503

SVXportal <= 2.5 admin/log.php Search Reflected XSS

State: Published
Severity: 5.1 Medium
Published: Feb 20, 2026
Updated: Jul 14, 2026
Reserved: Feb 19, 2026

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.
