Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

SQL Injection: Validation failures during IR generation could allow attackers to bypass standard parser restrictions and inject arbitrary payloads into database connection flows. Ensure SQL training labels are rigorously validated against the schema.
Input Validation: The math programming model generator executes dynamically generated expressions. Lack of token validation within expression builders can lead to untrusted variable injections executing directly in Pyomo.
Race Condition: Reusing global registry-mapped submitter pointers across concurrent user sessions creates a race condition that can result in session hijacking or incorrect cross-tenant code execution. Separate stateful instances must be instantiated per session.
