CVE-2025-36558Network attack vector

Browser script execution via reflected sso_token

Published May 1, 2025 · Updated May 2, 2025

Reflected XSS in KUNBUS Revolution Pi PiCtory 2.11.1 and earlier allows remote attackers to execute script via a crafted URL. The authentication flow reflects the sso_token value into its response without neutralizing embedded HTML script content. Exploitation requires a user to open the attacker-supplied URL; the script then runs in that user's PiCtory browser context.
