CVE-2026-121392 is fixed in freerdp3 on 1 platform by DEBIAN-CVE-2026-121392 (version 3.32.2+dfsg-1), released November 4, 2026. It is not reported as exploited. Patch Radar priority: Routine.
FreeRDP before 3.32.2 contains an improper certificate validation vulnerability in tls_verify_certificate() that accepts Common Name fallback despite non-matching SAN entries and matches IP literals against DNS strings. Man-in-the-middle attackers holding a certificate from a client-trusted CA can bypass server identity checks to intercept RDP sessions, including keystrokes, clipboard, and screen content.
