Browser Auth Flow

Adversarial probe of a site's authentication. Drives the login flow once, records the trajectory, then runs a configurable set of probes against the captured artifacts and live page. Output is a structured findings.md inside the RVF container.

When to use

• Pre-deployment audit of a new auth flow.
• Investigating a suspected token leak or redirect issue.
• Establishing a baseline for ongoing regression checks.

Steps

1. Open a recorded session via browser-record.

2. Drive the auth flow as in browser-login (credentials come from --credentials <handle> referencing browser-cookies if the run is a re-auth probe).

3. Run probes:

   • csrf: inspect the login POST in the trajectory; verify a same-origin token field is present and non-empty.
   • redirect: watch browser_get-url after each nav for cross-origin redirects with auth state in the URL or fragment. Flag any token-bearing URL that crosses an origin boundary.
   • cookie: walk document.cookie via browser_eval. For each cookie, check Secure, HttpOnly, SameSite, expiry, and entropy of the value. Flag missing flags or short tokens. Pass each through aidefence_scan to flag PII embedded in cookie values.
