TYPO3-EXT-SA-2026-012: SQL Injection in extension "Address List" (tt_address)

• Release Date: May 19, 2026
• Component Type: Third party extension. This extension is not a part of the TYPO3 default installation.
• Component: "Address List" (tt_address)
• Composer Package Name: friendsoftypo3/tt-address
• Vulnerability Type: SQL Injection
• Affected Versions: 10.0.0, 9.0.0 - 9.1.0, 8.1.1 and below
• Severity: Medium (rated lower than the CVSS score, as the vulnerable method is not invoked by the extension itself)
• Suggested CVSS v4.0: AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N
• References: CVE-2026-8827, CWE-89

Problem Description

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

Solution

Updated versions 10.0.1, 9.1.1 and 8.1.2 are available from the TYPO3 extension manager, packagist and at

https://extensions.typo3.org/extension/download/tt_address/10.0.1/zip
https://extensions.typo3.org/extension/download/tt_address/9.1.1/zip
https://extensions.typo3.org/extension/download/tt_address/8.1.2/zip

Users of the extension are advised to update the extension as soon as possible.
