CVE-2026-42218: Neutrinolabs Xrdp

Medium severity, CVSS 5.3. EPSS: 0.4% chance of exploitation in the next 30 days.

xrdp is an open source RDP server. Versions 0.10.6 and prior contain a timing side-channel vulnerability in the login interface. Due to a discrepancy in response processing times, a remote attacker can infer the existence of a username on the system, leading to unauthorized information disclosure via username enumeration. This issue has been fixed in version 0.10.6.1.

Affected products

• Neutrinolabs Xrdp: before 0.10.6.1 (fixed in 0.10.6.1)
