CVE-2026-76796 Newell Brands CVE debrief
CVE-2026-76796 is a medium-severity vulnerability in the Newell Brands DYMO Connect Desktop local web service. The LoadImageAsPngBase64 endpoint 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. The issue was fixed in version 1.6.2, but the fix only limits access by file extension, not by directory, leaving residual risk for arbitrary-location reads of files with allowed image extensions.

Who should care
Defenders responsible for DYMO Connect Desktop deployments should assess exposure and prioritize verification and remediation efforts. This vulnerability may impact organizations using DYMO Connect Desktop, particularly if they have not upgraded to version 1.6.2 or later.
Why it matters
CVE-2026-76796 is a medium-severity vulnerability in DYMO Connect Desktop that allows for potential reads of arbitrary image files. Defenders should prioritize verification, remediation, and compensating controls to mitigate the risk.
- Potential reads of arbitrary image files from the host filesystem
- Residual risk due to limited fix by file extension only
- Verification priority for DYMO Connect Desktop deployments
- Compensating controls may be necessary to restrict file system access
Technical summary
The LoadImageAsPngBase64 endpoint of the Newell Brands DYMO Connect Desktop local web service is vulnerable to arbitrary file reads due to inadequate validation of the file path parameter. This allows an attacker to read image files from the host filesystem outside the intended scope. The issue was addressed in version 1.6.2 by limiting access based on file extension, but not directory, leaving some residual risk.
Defensive priority
Defenders should prioritize verifying exposure and implementing compensating controls, as the vulnerability allows for potential reads of arbitrary image files.
Recommended defensive actions
- Verify DYMO Connect Desktop version and upgrade to 1.6.2 or later if vulnerable
- Implement compensating controls to restrict file system access
- Monitor for potential anomalous reads of image files
- Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance.
- Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed.
- Check relevant monitoring, detection, and logs for exposed assets that need extra review.
- Track exceptions, retest remediated assets, and close the item only after evidence is documented.
Evidence notes
The CVE record and NVD entry provide details on the vulnerability, but evidence is limited regarding actual exploitation or affected versions beyond the fixed version 1.6.2. 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. The issue was fixed in version 1.6.2, but the fix only limits access by file extension, not by directory,
