phpMyAdmin SQL injection vulnerability

CVE-2020-10802GHSA-f4cr-3xmc-2wpm

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (phpmyadmin/phpmyadmin 5.0.2, 4.9.5), 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.

# Patch Next advisory brief: CVE-2020-10802

Advisory: phpMyAdmin SQL injection vulnerability
IDs: CVE-2020-10802, GHSA-f4cr-3xmc-2wpm
Record: https://patchnext.com/advisories/cve-2020-10802 (revision 1, source checked 26 Oct 2026, 14:20 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.0)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: phpmyadmin/phpmyadmin 5.0.2, 4.9.5. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist phpmyadmin/phpmyadmin: affected >= 4.9.0, < 4.9.5; >= 5.0.0, < 5.0.2; fixed in 4.9.5, 5.0.2

## Suggested inspection (read-only)
- Packagist phpmyadmin/phpmyadmin: 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 phpmyadmin/phpmyadmin.
- 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-f4cr-3xmc-2wpm (GitHub-reviewed advisory GHSA-f4cr-3xmc-2wpm lists affected ranges: Packagist phpmyadmin/phpmyadmin >=4.9.0 =5.0.0 <5.0.2)

Commands are suggestions: review each one before running it.
