Lit Template Binding Audit

Finds the lit-html binding positions auto-escaping does not cover, before the component ships

Install

npx @readystack/lit-binding-xss-audit file

Node 18+. The same 15 rules as the VS Code extension, from a terminal or CI.

Free

• Audit the Lit component file you have open and get every unsafe binding with its line number and the safe form to write instead.
• --rules lists every rule

With a licence ($29 once)

• Scans every component in the workspace and exports one dated evidence report: each unsafe binding with its file, line and safe form.

@readystack/lit-binding-xss-audit --dir ./templates --report html --out report.html

An application-security contractor reviewing component code bills roughly 150 to 250 an hour; this audit runs on the file you have open.
