CVE-2026-55626
8.0 · HIGHOverview
CVE-2026-55626 is a high-severity vulnerability affecting neutrinolabs xrdp. It was published on July 20, 2026 and has a CVSS 3.1 base score of 8.0 (HIGH).
This vulnerability has a CVSS 3.1 base score of 8.0, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical Description
xrdp is an open source RDP server. In versions 0.10.6 and prior, when an authenticated user session is initialized using the Xvnc backend over UNIX domain sockets, the Xvnc process is launched with insufficient authentication mechanisms. A local authenticated attacker could exploit this vulnerability to bypass intended session isolation, allowing them to unauthorizedly view or control the active desktop sessions of other users on the same system. Users using other backends, such as xorgxrdp or Xvnc over TCP sockets, are not affected. This issue has been fixed in version 0.10.6.1.
Remediation
Check the references section for vendor advisories and patches from neutrinolabs. Update xrdp to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
