gitverify has improper tag signature verification

GHSA-h829-5cg7-6hff

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (github.com/supply-chain-tools/gitverify 0.0.0-20260421124901-c2c60da05d5c), 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.

Source description

As published by the source; long descriptions are shortened.

gitverify is still a prototype. Impact The bug is related to requireSignedTags which is on by default: an unsigned annotated tag would pass the verification. The commit pointed to by the tag would still have to be signed by a maintainer or a contributor. Patches Since the initial commit, fixed in c2c60da05d5c73621d0ce7ea02770bacd79ec8b1 (no semantic versions yet). Workarounds No

# Patch Next advisory brief: GHSA-h829-5cg7-6hff

Advisory: gitverify has improper tag signature verification
IDs: GHSA-h829-5cg7-6hff
Record: https://patchnext.com/advisories/ghsa-h829-5cg7-6hff (revision 1, source checked 26 Oct 2026, 15:19 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: github.com/supply-chain-tools/gitverify 0.0.0-20260421124901-c2c60da05d5c. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go github.com/supply-chain-tools/gitverify: affected < 0.0.0-20260421124901-c2c60da05d5c; fixed in 0.0.0-20260421124901-c2c60da05d5c

## Suggested inspection (read-only)
- Go github.com/supply-chain-tools/gitverify: 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/supply-chain-tools/gitverify.
- 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-h829-5cg7-6hff (GitHub-reviewed advisory GHSA-h829-5cg7-6hff lists affected ranges: Go github.com/supply-chain-tools/gitverify >=0 <0.0.0-20260421124901-c2c60da05d5c)
