Description
FreeRDP before 3.29.0 fails to properly validate server-supplied RDPDR paths in drive redirection, allowing attackers to access prefix-sibling paths outside the configured shared root. A malicious RDP server can read, write, delete, and enumerate files in sibling directories by sending non-rooted paths that bypass the shared-root boundary check.
