phpMyAdmin Denial Of Service (DOS) attack

CVE-2016-5706GHSA-9rmm-8fp4-26hv

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (phpmyadmin/phpmyadmin 4.6.3, 4.4.15.7, 4.0.10.16), 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

js/getscripts.js.php in phpMyAdmin 4.0.x before 4.0.10.16, 4.4.x before 4.4.15.7, and 4.6.x before 4.6.3 allows remote attackers to cause a denial of service via a large array in the scripts parameter.

# Patch Next advisory brief: CVE-2016-5706

Advisory: phpMyAdmin Denial Of Service (DOS) attack
IDs: CVE-2016-5706, GHSA-9rmm-8fp4-26hv
Record: https://patchnext.com/advisories/cve-2016-5706 (revision 1, source checked 26 Oct 2026, 14:33 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.5)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: phpmyadmin/phpmyadmin 4.6.3, 4.4.15.7, 4.0.10.16. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist phpmyadmin/phpmyadmin: affected >= 4.0, < 4.0.10.16; >= 4.4, < 4.4.15.7; >= 4.6, < 4.6.3; fixed in 4.6.3, 4.4.15.7, 4.0.10.16

## 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-9rmm-8fp4-26hv (GitHub-reviewed advisory GHSA-9rmm-8fp4-26hv lists affected ranges: Packagist phpmyadmin/phpmyadmin >=4.0 =4.4 =4.6 <4.6.3)
