phpMyAdmin SQL Injection
CVE-2020-10804GHSA-h65r-8fp8-w7cx
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.
In phpMyAdmin 4.x before 4.9.5 and 5.x before 5.0.2, a SQL injection vulnerability was found in retrieval of the current username (in libraries/classes/Server/Privileges.php and libraries/classes/UserPassword.php). A malicious user with access to the server could create a crafted username, and then trick the victim into performing specific actions with that user account (such as editing its privileges).

# Patch Next advisory brief: CVE-2020-10804 Advisory: phpMyAdmin SQL Injection IDs: CVE-2020-10804, GHSA-h65r-8fp8-w7cx Record: https://patchnext.com/advisories/cve-2020-10804 (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-h65r-8fp8-w7cx (GitHub-reviewed advisory GHSA-h65r-8fp8-w7cx lists affected ranges: Packagist phpmyadmin/phpmyadmin >=4.9.0 =5.0.0 <5.0.2) Commands are suggestions: review each one before running it.
