CVE-2026-50003 is a critical path traversal vulnerability in OFFIS DCMTK affecting clients that use bit-preserving C-GET storage mode, including configurations such as getscu --bit-preserving or DCMSCU_STORAGE_BIT_PRESERVING. A malicious or compromised DICOM server can supply file paths that are not properly constrained to the client-selected output directory, allowing use of both relative traversal sequences such as ../ and absolute paths. As a result, the DCMTK client may create or truncate files outside the intended destination directory during C-GET storage handling.
