Newell Brands DYMO ID 1.5.1.71 resolves its plugin Modules directory relative to the process working directory. An attacker could store a job file alongside malicious modules / DLL that sets the process working directory to the job file's folder when a victim clicks on the file, resulting in code execution at the victim's privilege level. Fixed in 1.6.0.

The LoadImageAsPngBase64 endpoint of the Newell Brands DYMO Connect Desktop local web service accepts a file path parameter without adequate validation, allowing a crafted path to read arbitrary image files from the host filesystem outside the intended scope. Fixed in 1.6.2. The fix limits access by file extension only, not by directory - arbitrary-location reads of files with an allowed image extension remain possible by design (accepted residual risk).

Newell Brands DYMO ID 1.5.1.71 parses job files using XmlDocument.Load() without disabling DTD processing. The PC Job Files view automatically parses every recognized job file extension on folder browse. A crafted file on any browsed network share can perform SSRF, capture NTLMv2 credentials, read local files, or crash the process. Fixed in 1.6.0.
