CVE-2023-6981Network attack vector

Database disclosure via unparameterized subscriber group filter

Published Jan 3, 2024 · Updated Apr 8, 2026

SQL injection in VeronaLabs WSMS 6.5 and earlier allows remote authenticated users to extract database data via group_id. The get_data() method in class-wpsms-subscribers-table.php interpolates the subscriber group filter directly into SQL instead of binding it as an integer parameter. Contributor-level access reaches the injection, while reflected cross-site scripting additionally requires a victim to open the crafted response.
