Taint tracking in Python

Overview

Taint tracking tracks how arbitrary values, "taint", flow throughout the program. This is useful for finding whether potentially malicious input can be used in an insecure way, whether dangerous arguments are passed to vulnerable functions, and whether confidential or sensitive data can leak. It is also useful for tracking invalid, insecure, or untrusted data in other analyses.

// Extending taint-tracking to support tracking through iteration is a bit fiddly prior in 1.20 and earlier
// We need to track both getting an item from the iterable *and* the assignment to the target variable.

/* Track the implicit `next` operation */

    ForNode for;
