database-query

This module is not overtly malicious, but it contains clear insecure coding patterns that enable SQL injection (interpolation of user-controlled table names and values into SQL). It also lacks proper resource management and contains a syntax error. Recommend: fix by using parameterized queries for values, validate or whitelist table names (do not interpolate identifiers), enforce type-checking for IDs, use context managers to close connections, and correct the syntax error. Treat the code as insecure until fixed.

The descriptor clearly documents critical SQL injection risks: user inputs are concatenated into SQL queries in functions such as search_users and get_user_by_id despite claimed parameterized queries. This yields a high-security risk (possible data exfiltration and tampering). Treat the module as unsafe until queries are rewritten to use proper parameterization and input validation.
