Record: https://patchnext.com/advisories/cve-2014-8739 (revision 1, source checked 26 Oct 2026, 14:20 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Unrated
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist blueimp/jquery-file-upload: affected >= 6.4.4, <= 6.4.4

## Suggested inspection (read-only)
- Packagist blueimp/jquery-file-upload: check the installed version with your package manager.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on blueimp/jquery-file-upload.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
