Doc Text:
A flaw was found in FreeRDP, an open-source implementation of the Remote Desktop Protocol (RDP). This vulnerability allows a malicious RDP server to bypass security checks during drive redirection. By sending specially crafted paths, the server can access, read, write, delete, and list files in directories outside the intended shared folder on the client's system. This could lead to unauthorized access and manipulation of sensitive data.

Description OSIDB Bzimport 2026-08-01 13:02:30 UTC
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.
