CVE-2023-7331Network attack vector

SQL injection via concatenated user inputs

Published Dec 31, 2025 · Updated Dec 31, 2025

SQL injection in PKrystian Full Stack Bank allows remote authenticated users to manipulate user database queries through crafted form values. Vulnerable PHP user handlers concatenate login, registration, session-lookup, and account identifiers directly into SQL statements rather than binding them as parameters. The published assessment requires high privileges, and successful exploitation can expose or alter user records or interrupt database-backed operations.
