CVE-2026-109953
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.
Does this matter?
Lower severity and a low EPSS score (0.27%). Track it; it rarely justifies an emergency change on its own.
Description
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.
