Denial of Service in dhowden/tag

CVE-2020-29242GHSA-9xm8-8qvc-vw3p

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (github.com/dhowden/tag 0.0.0-20201120070457-d52dcb253c63), 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-2020-29242

Advisory: Denial of Service in dhowden/tag
IDs: CVE-2020-29242, GHSA-9xm8-8qvc-vw3p
Record: https://patchnext.com/advisories/cve-2020-29242 (revision 1, source checked 26 Oct 2026, 15:04 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 4.8)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: github.com/dhowden/tag 0.0.0-20201120070457-d52dcb253c63. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go github.com/dhowden/tag: affected < 0.0.0-20201120070457-d52dcb253c63; fixed in 0.0.0-20201120070457-d52dcb253c63

## Suggested inspection (read-only)
- Go github.com/dhowden/tag: check the installed version with your package manager.

## 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 github.com/dhowden/tag.
- 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://github.com/advisories/GHSA-9xm8-8qvc-vw3p (GitHub-reviewed advisory GHSA-9xm8-8qvc-vw3p lists affected ranges: Go github.com/dhowden/tag >=0 <0.0.0-20201120070457-d52dcb253c63)
