Doc Text:
A flaw was found in FreeRDP. A malicious Remote Desktop Protocol (RDP) server can uncover a user's smartcard Personal Identification Number (PIN) through unrestricted brute-force authentication attempts. Because the virtual smartcard component resets the retry counter on each new connection handle rather than enforcing a persistent limit, an attacker can bypass attempt restrictions when a client connects with virtual smartcard authentication enabled. Successful exploitation allows the malicious server to recover the smartcard PIN and perform unauthorized cryptographic operations with the user's credentials.

Description OSIDB Bzimport 2026-10-13 13:48:10 UTC 
FreeRDP 3.0.0 before 3.32.0 contains an improper restriction of excessive authentication attempts in its virtual smartcard GIDS implementation, which stores the PIN retry counter per-handle. A malicious RDP server can exhaust the counter with VERIFY APDUs, then request a new SCardConnect to reset attempts, enabling unbounded online brute-forcing of the configured smartcard PIN.
