Browser script execution via reflected logout input
Published Apr 17, 2023 · Updated Feb 6, 2025
Affected ServiceNow Now Platform releases contain reflected XSS in logout that lets remote attackers run JavaScript in a user's web console. ServiceNow has not disclosed which logout parameter is reflected or where output encoding fails, so the precise input-to-response path is not public. Exploitation requires no account but does require a user to follow a crafted logout request, with resulting script access limited to that user's browser context.
