SQL Injection in TYPO3 Frontend Login

GHSA-j86x-pjmr-9m6w

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (typo3/cms 7.6.10, 6.2.26), 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: GHSA-j86x-pjmr-9m6w

Advisory: SQL Injection in TYPO3 Frontend Login
IDs: GHSA-j86x-pjmr-9m6w
Record: https://patchnext.com/advisories/ghsa-j86x-pjmr-9m6w (revision 1, source checked 26 Oct 2026, 14:25 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.4)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: typo3/cms 7.6.10, 6.2.26. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist typo3/cms: affected >= 6.2.0, < 6.2.26; >= 7.6.0, < 7.6.10; fixed in 7.6.10, 6.2.26

## Suggested inspection (read-only)
- Packagist typo3/cms: 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 typo3/cms.
- 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-j86x-pjmr-9m6w (GitHub-reviewed advisory GHSA-j86x-pjmr-9m6w lists affected ranges: Packagist typo3/cms >=6.2.0 =7.6.0 <7.6.10)

Commands are suggestions: review each one before running it.
