CVE-2026-33516 is fixed in xrdp on 1 platform, first by DEBIAN-CVE-2026-33516, released April 17, 2026. It is not reported as exploited. Patch Radar priority: Urgent.
xrdp is an open source RDP server. Versions through 0.10.5 contain an out-of-bounds read vulnerability during the RDP capability exchange phase. The issue occurs when memory is accessed before validating the remaining buffer length. A remote, unauthenticated attacker can trigger this vulnerability by sending a specially crafted Confirm Active PDU. Successful exploitation could lead to a denial of service (process crash) or potential disclosure of sensitive information from the process memory. This issue has been fixed in version 0.10.6.
