=== Testing Header Exposure in Session Cookie === [4/6] Analyzing the vulnerable code pattern... === VULNERABILITY ANALYSIS === ✅ VULNERABILITY CONFIRMED - Vulnerable code pattern detected The code contains: `session.headers = headers` This stores ALL HTTP headers in the session cookie. Impact: Internal proxy headers (x-forwarded-for, x-api-key, x-real-ip, authorization, etc.) are base64-encoded in the cookie and can be decoded by anyone with access to the cookie. Code section: --- 171: session.redirect = redirect 172: session.query = restQuery >>> 173: session.headers = headers 174: 175: return this.handler('GET', handlerParams, {}) 176: } --- === PROOF OF VULNERABILITY === Example: When a request contains these headers: { "x-forwarded-for": "10.0.0.1", "x-internal-api-key": "sk_live_secret123", "x-real-ip": "192.168.1.1", "authorization": "Bearer secret_token", "cookie": "other_session=secret_value" } The session cookie will contain (base64 encoded): eyJoZWFkZXJzIjp7IngtZm9yd2FyZGVkLWZvciI6IjEwLjAuMC4xIiwieC1pbnRlcm5hbC1hcGkta2V5... Anyone can decode this to reveal the headers: {"headers":{"x-forwarded-for":"10.0.0.1","x-internal-api-key":"sk_live_secret123","x-real-ip":"192.1... === RISK ASSESSMENT === HIGH: Internal infrastructure details, API keys, and sensitive tokens can be exposed to any client that can read the session cookie.
