Description Vipul Nair 2026-10-27 10:20:29 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

FreeRDP shadow server from 3.0.0 before 3.32.0 dispatches input PDUs during the Confirm Active state before authentication, allowing unauthenticated attackers to inject keyboard input. Attackers can negotiate TLS-only RDP and send an input PDU without Confirm Active to inject synthetic keystrokes into the host user's X11 session via XTEST.
Comment 1 Ondrej Holy 2026-11-02 15:09:45 UTC 
Fixed in FreeRDP 3.32.0 (upstream). Fedora 43, 44, 45 and Rawhide ship freerdp 3.32.2, which contains the fix. Closing as ERRATA.
