CVE-2024-33866Network attack vector

Authenticated script execution via DocumentTemplate output

Published May 14, 2024 · Updated Feb 13, 2025

Cross-site scripting in linqi for Windows before 1.4.0.1 allows remote authenticated users to execute scripts in a victim's browser. The /api/DocumentTemplate/{GUID} endpoint renders attacker-controlled content without sufficient neutralization during web page generation. Exploitation requires low-privileged access and victim interaction; execution occurs within the victim's browser context.
