Privilege Escalation in TYPO3 CMS
What to do
Vendor fix available. Upgrade each affected package to the fixed version on its release line (typo3/cms 8.0.1, 7.6.5, 6.2.20), 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.
The workspace/ version preview link created by a privileged (backend) user could be abused to obtain certain editing permission, if the admin panel is configured to be shown. A valid preview link is required to exploit this vulnerability.

# Patch Next advisory brief: GHSA-v5jp-4h2p-j2p4 Advisory: Privilege Escalation in TYPO3 CMS IDs: GHSA-v5jp-4h2p-j2p4 Record: https://patchnext.com/advisories/ghsa-v5jp-4h2p-j2p4 (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 6.5) Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV. Vendor response: Vendor fix available; fixed versions by package: typo3/cms 8.0.1, 7.6.5, 6.2.20. A vendor fix does not mean a deployment is fixed. ## Affected components - Packagist typo3/cms: affected >= 6.2.0, < 6.2.20; >= 7.6.0, < 7.6.5; >= 8.0.0, < 8.0.1; fixed in 6.2.20, 7.6.5, 8.0.1 ## 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-v5jp-4h2p-j2p4 (GitHub-reviewed advisory GHSA-v5jp-4h2p-j2p4 lists affected ranges: Packagist typo3/cms >=6.2.0 =7.6.0 =8.0.0 <8.0.1) Commands are suggestions: review each one before running it.
