CVE-2026-8827: TYPO3 SQL Injection in extension "Address List" (tt_address)

May 19, 2026 (updated June 29, 2026)

In the TYPO3 extension tt_address, 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.
