Remote path traversal via symlink following in zrok's WebDAV drive backend allows unauthenticated network attackers to read arbitrary files accessible to the zrok process and overwrite critical system files (such as SSH authorized_keys) outside the intended share boundary. Attack complexity is high because exploitation requires a pre-existing symlink inside the shared directory pointing outside DriveRoot-a precondition typically created through local access or misconfiguration, not by the attacker. EPSS data not provided; no CISA KEV listing indicates targeted rather than widespread exploitation. Vendor-released patch available in version 2.0.2 with commit 459bcfc1e121decae1b1d11c37ad94e4ed5bbf2e implementing symlink boundary validation.
