TYPO3 SQL Injection in extension "Address List" (tt_address)

CVE-2026-8827GHSA-3h52-6v6j-6wwv

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (friendsoftypo3/tt-address 10.0.1, 9.1.1, 8.1.2), 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 the TYPO3 extension ttaddress, the AddressRepository::getSqlQuery() method constructs a database query without properly sanitizing user input, leading to SQL Injection. The method is not invoked anywhere within the extension itself and therefore poses no direct risk in a default installation. However, custom extensions that call this method with untrusted input would expose the site to SQL injection. This has been patched in version 8.1.2, 9.1.1, and 10.0.1.

# Patch Next advisory brief: CVE-2026-8827

Advisory: TYPO3 SQL Injection in extension "Address List" (tt_address)
IDs: CVE-2026-8827, GHSA-3h52-6v6j-6wwv
Record: https://patchnext.com/advisories/cve-2026-8827 (revision 1, source checked 26 Oct 2026, 14:49 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.2)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: friendsoftypo3/tt-address 10.0.1, 9.1.1, 8.1.2. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist friendsoftypo3/tt-address: affected >= 10.0.0, < 10.0.1; >= 9.0.0, < 9.1.1; < 8.1.2; fixed in 10.0.1, 8.1.2, 9.1.1

## Suggested inspection (read-only)
- Packagist friendsoftypo3/tt-address: 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 friendsoftypo3/tt-address.
- 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-3h52-6v6j-6wwv (GitHub-reviewed advisory GHSA-3h52-6v6j-6wwv lists affected ranges: Packagist friendsoftypo3/tt-address >=10.0.0 =9.0.0 =0 <8.1.2)
