CVE-2025-40616Network attack vector

Browser script execution via reflected IDRESERVA input

Published Apr 29, 2025 · Updated Apr 29, 2025

Reflected XSS in AGENDIC SOFTWARE S.L. Bookgy allows remote attackers to execute JavaScript in a victim's browser via a malicious URL. The /bkg_imprimir_comprobante.php endpoint reflects the untrusted IDRESERVA parameter into a generated page without sufficient output neutralization. Exploitation requires the victim to open the attacker-supplied URL and allows the script to read or modify data available to that page's browser context.
