CVE-2025-48987Public exploitNetwork attack vector

Administrator script execution via unsanitized group parameter

Published Nov 20, 2025 · Updated Nov 20, 2025

Reflected XSS in Revive Adserver 5.5.2 and 6.0.1 and earlier allows remote attackers to execute scripts via a crafted URL. The account-preferences-plugin.php script writes the group query parameter into HTML, JavaScript, or CSS output without proper sanitization. Exploitation requires a logged-in administrator to visit the crafted URL, after which the payload executes in that administrator's browser context.
