# Patch Next advisory brief: CVE-2022-0083

Advisory: User enumeration in livehelperchat
IDs: CVE-2022-0083, GHSA-4xww-6h7v-29jg
Record: https://patchnext.com/advisories/cve-2022-0083 (revision 1, source checked 26 Oct 2026, 14:04 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 fix available; fixed versions by package: remdex/livehelperchat 3.91. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist remdex/livehelperchat: affected < 3.91; fixed in 3.91

## Suggested inspection (read-only)
- Packagist remdex/livehelperchat: 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 remdex/livehelperchat.
- 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-4xww-6h7v-29jg (GitHub-reviewed advisory GHSA-4xww-6h7v-29jg lists affected ranges: Packagist remdex/livehelperchat >=0 <3.91)
