Description OSIDB Bzimport 2026-10-21 01:03:16 UTC 
FreeRDP from 2.0.0 before 3.32.0 contains an improper certificate validation vulnerability in its proxy that accepts untrusted target TLS certificates when no verification module is configured. Network-positioned attackers can intercept the proxy's outbound connection and present a self-signed, wrong-hostname certificate to impersonate the RDP target and receive proxied session data.
