CVE-2026-8827

HIGH

8.2

CVSS v4

NVD

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.
