CVE-2026-67295Network attack vectorHinoki check available

Sibling-file access via unseparated RDPDR path concatenation

Published Aug 1, 2026 · Updated Aug 1, 2026

Path traversal in FreeRDP before 3.29.0 allows remote attackers to access prefix-sibling files through RDPDR drive redirection. The drive_file_combine_fullpath() helper appends a server-supplied non-rooted path directly to the shared base path without inserting a separator or enforcing containment. Exploitation requires a client to connect to a malicious or compromised RDP server with drive redirection enabled; access is limited to sibling paths sharing the root's string prefix.
