Summary
FFmpeg before 7.1.4 and from 8.0 before 8.0.2 is affected. The ff_rtsp_connect() function follows RTSP 3xx redirects without validating the Location URL, a server-side request forgery flaw (CWE-918). A malicious RTSP server can redirect FFmpeg to internal hosts and ports under other schemes, bypassing -protocol_whitelist, to probe internal network services.
