VulnerabilityLive — needs Playwright3 checks
Browser Storage & Session Token Scanner
Detect JWTs, refresh tokens, and session identifiers stored in localStorage or sessionStorage.
How this scan works
- Loads the page in headless Chromium (Playwright)
- Reads localStorage/sessionStorage after load, and again after a short idle for async hydration
- Regex-matches JWT shape and common token key names (access_token, refresh_token, session)
- Flags long-lived tokens in storage as an XSS-exfiltration risk vs. httpOnly cookies
