Authenticated SSRF via attacker-controlled URL fetch
Published Mar 31, 2025 · Updated Mar 31, 2025
Server-side request forgery in Youkefu 4.2.0 allows remote authenticated users to make server-originated requests through /res/url. The handler uses the attacker-controlled url argument as the request destination; public records do not identify the underlying function or filtering failure. Low-privileged access is required, and requests can reach resources accessible from the application server's network position.
