CVE-2023-31456Network attack vector

Authenticated internal resource access via server-side request forgery

Published Jul 16, 2024 · Updated Nov 7, 2024

Server-side request forgery in Fluid Topics before 4.3 allows remote authenticated users to make arbitrary internal or external requests. Public records identify the platform server as the request origin but do not disclose the affected endpoint or exact destination-validation failure. Exploitation requires authenticated access and user interaction; resulting requests can reach resources that are not directly accessible to the user.
