Doc Text:
A flaw was found in FreeRDP. When connecting using the restricted admin mode option, the client fails to suppress credential delegation, inadvertently transmitting administrative credentials in cleartext to the remote server. A compromised destination host or an on-path attacker can intercept these credentials, resulting in sensitive information disclosure and potential unauthorized administrative access.

Description OSIDB Bzimport 2026-10-13 13:48:59 UTC 
FreeRDP 3.0.0 before 3.32.0 contains an insufficiently protected credentials vulnerability where the /restricted-admin option fails to suppress CredSSP credential delegation, sending the cleartext password to the RDP server. A compromised or man-in-the-middle destination host can decode TSPasswordCreds and the Client Info PDU to obtain reusable administrative domain, username, and password values.
