Description OSIDB Bzimport 2026-10-12 16:53:25 UTC
FreeRDP 3.0.0 before 3.32.0 contains an improper certificate validation vulnerability in freerdp_http_request() in libfreerdp/utils/http.c that completes TLS handshakes without verifying the server certificate chain. On-path attackers can impersonate login.microsoftonline.com in the Azure AD authentication flow to capture OAuth authorization codes and substitute the OpenID discovery document.
