CVE-2026-32105 is an integrity-validation vulnerability in xrdp versions through 0.10.5. When the Classic RDP Security layer is used, xrdp generates MAC signatures for encrypted RDP packets but does not validate the received 8-byte integrity signature. Consequently, modified encrypted packets are accepted without detecting tampering. TLS-protected connections are not affected.
