CVE-2026-38361

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (dash-uploader 0.7.0a1), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

# Patch Next advisory brief: CVE-2026-38361

Advisory: PYSEC-2026-37
IDs: CVE-2026-38361
Record: https://patchnext.com/advisories/cve-2026-38361 (revision 1, source checked 24 Oct 2026, 04:13 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.5)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: dash-uploader 0.7.0a1. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI dash-uploader: affected >= 0.1.0, < 0.7.0a1; fixed in 0.7.0a1

## Suggested inspection (read-only)
- `python -m pip show dash-uploader`: prints the installed version. Run with the environment that serves production active.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on dash-uploader.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://osv.dev/vulnerability/PYSEC-2026-37 (OSV record PYSEC-2026-37 lists affected ranges: PyPI dash-uploader >=0.1.0 <0.7.0a1 (fixed))
