code/js-cookie-httponly-false

Cookie set with httpOnly: false in auth context

highCode regexinsecure-cookieCWE-1004js

What it detects

Auth/session cookies should always be HttpOnly so client-side scripts can't read them, eliminating cookie-stealing XSS. AI-generated cookie middleware often omits httpOnly or sets it to false to enable client JS reads.

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.
