EPSS

• CVE-2018-19968: 2.89% estimated exploitation activity in the next 30 days; percentile 86.90 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

An attacker can exploit phpMyAdmin before 4.8.4 to leak the contents of a local file because of an error in the transformation feature. The attacker must have access to the phpMyAdmin Configuration Storage tables, although these can easily be created in any database to which the attacker has access. An attacker must have valid credentials to log in to phpMyAdmin; this vulnerability does not allow an attacker to circumvent the login system.

# Patch Next advisory brief: CVE-2018-19968

Advisory: phpMyAdmin Local file inclusion through transformation feature
IDs: CVE-2018-19968, GHSA-xc97-r49q-cxgc
Record: https://patchnext.com/advisories/cve-2018-19968 (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: Medium (CVSS 6.5)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: phpmyadmin/phpmyadmin 4.8.4. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist phpmyadmin/phpmyadmin: affected < 4.8.4; fixed in 4.8.4

## 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-xc97-r49q-cxgc (GitHub-reviewed advisory GHSA-xc97-r49q-cxgc lists affected ranges: Packagist phpmyadmin/phpmyadmin >=0 <4.8.4)
