Docs through 5.6.1 contains a server-side request forgery vulnerability in the cors-proxy endpoint that allows anonymous attackers to make outbound requests by providing a public document UUID. Attackers can exploit DNS time-of-check-time-of-use race conditions and shared address space bypasses to access internal network resources and exfiltrate image content.
