## What is CVE-2026-76796?

CVE-2026-76796 is a medium-severity path traversal vulnerability in Newell Brands DYMO Connect Desktop, published on 15 Sep 2026. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

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).

Weakness: CWE-73 (External Control of File Name or Path)
