XSS: document.write called with a variable
What it detects
document.write with untrusted data injects script into the page. Avoid entirely in modern code.
How it runs
Applied line-by-line via a tagged regex with language-specific gating. Comments are skipped. Designed for high-confidence patterns where AST parsing would be overkill.
