🛡️ Sentinel: [CRITICAL] Fix SQL injection in duckdb_adapter - #99
Conversation
Replaced vulnerable f-string interpolations for start_time and end_time in the DuckDB adapter layer with secure parameterized queries (`?`). Removed the inadequate string escaping logic and updated the associated unit tests to correctly verify the parameters. Co-authored-by: aperetti <482392+aperetti@users.noreply.github.com>

🚨 Severity: CRITICAL
💡 Vulnerability: SQL Injection in DuckDB adapter. The adapter used Python f-strings to concatenate the
start_timeandend_timearguments directly into the SQL query strings. The manual attempt to sanitize single quotes (start_time.replace("'", "''")) was fragile and incomplete, allowing for SQL injection vulnerabilities.🎯 Impact: If
start_timeorend_timearguments were user-controlled, an attacker could inject arbitrary SQL to manipulate database logic, extract sensitive analytics data, or potentially perform a Denial-of-Service via expensive queries.🔧 Fix: Replaced f-string interpolations with secure parameterized query markers (
?::TIMESTAMP) and passedstart_timeandend_timeas parameter arrays to theconn.execute()method calls. Removed the fragile manual replace logic. Updated the associatedpytestassertions.✅ Verification: Verified by executing
pytest tests/test_duckdb_adapter.py, which correctly executes the queries and tests that parameters are securely extracted into the query parameter list.PR created automatically by Jules for task 18234672885262939690 started by @aperetti
