Summary
Vulnerability reported (CVE-2026-76796). Risk of unauthorized operations or information disclosure. Mitigation: upgrade to 1.6.2 or later.
Original description
The description as published by the source.
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).
