CVE-2023-32082GHSA-3p4g-rcw5-8298

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (github.com/etcd-io/etcd 3.5.9, 3.4.26), 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.

Impact LeaseTimeToLive API allows access to key names (not value) associated to a lease when Keys parameter is true, even a user doesn't have read permission to the keys. The impact is limited to a cluster which enables auth (RBAC). Patches < v3.4.26 and < v3.5.9 are affected. Workarounds No. Reporter Yoni Rozenshein

# Patch Next advisory brief: CVE-2023-32082

Advisory: etcd Key name can be accessed via LeaseTimeToLive API
IDs: CVE-2023-32082, GHSA-3p4g-rcw5-8298
Record: https://patchnext.com/advisories/cve-2023-32082 (revision 1, source checked 26 Oct 2026, 15:00 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Low (CVSS 3.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: github.com/etcd-io/etcd 3.5.9, 3.4.26. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go github.com/etcd-io/etcd: affected < 3.4.26; >= 3.5.0, < 3.5.9; fixed in 3.5.9, 3.4.26

## Suggested inspection (read-only)
- Go github.com/etcd-io/etcd: 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/etcd-io/etcd.
- 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-3p4g-rcw5-8298 (GitHub-reviewed advisory GHSA-3p4g-rcw5-8298 lists affected ranges: Go github.com/etcd-io/etcd >=0 =3.5.0 <3.5.9)

Commands are suggestions: review each one before running it.
