CVE-2024-37146Network attack vector

Browser script execution via reflected credential ID

Published Jul 1, 2024 · Updated Aug 2, 2024

Reflected XSS in Flowise 1.4.3 and earlier allows remote attackers to run script in a user's browser via a crafted credentials URL. The GET handler for /api/v1/credentials/:id inserts an unknown credential ID into an HTML 404 response without neutralizing it. Default deployments require no authentication, but a user must load the crafted URL; script runs in the Flowise origin and can read or alter browser-accessible data.
