What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (xataface/xataface 3.0.0), 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-2021-4303

Advisory: Xataface vulnerable to Cross-site Scripting
IDs: CVE-2021-4303, GHSA-64wv-c7jw-jw2q
Record: https://patchnext.com/advisories/cve-2021-4303 (revision 1, source checked 26 Oct 2026, 14:10 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: xataface/xataface 3.0.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist xataface/xataface: affected < 3.0.0; fixed in 3.0.0

## Suggested inspection (read-only)
- Packagist xataface/xataface: 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 xataface/xataface.
- 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-64wv-c7jw-jw2q (GitHub-reviewed advisory GHSA-64wv-c7jw-jw2q lists affected ranges: Packagist xataface/xataface >=0 <3.0.0)
