Analyzing the "Zero Auth" vulnerability discovered by Alex Schapiro and demonstrating how a declarative, edge-safe approach would neutralize the attack.

Recently, security researcher Alex Schapiro published an alarming analysis on how he gained full access to over 100,000 confidential files from a law firm using Filevine (valued at over $1 billion).

The attack vector was frighteningly simple:

  1. An API endpoint (/recommend) exposed without any authentication.
  2. A JSON response that inadvertently returned a boxToken with full admin privileges.

There was no need for complex SQL Injection or social engineering. Just an empty POST request and the "back door" swung open.

Today, I'll show how the Beddel architecture, specifically an agent running as middleware (Edge-Safe), would have blocked this attack across three different layers using only native protocol resources.

The Beddel Philosophy: "Security by Schema"

In Beddel, security isn't an "if" statement lost in the middle of controller code. Security is declarative. If it's not in the contract (Schema), it doesn't get in and it doesn't get out.

To protect the Filevine API, we would deploy a middleware agent (FilevineGuardian) intercepting calls. Let's look at the code.

The Protection Agent (guardian.yaml)

# Filevine Guardian Agent
# Security middleware for protecting critical endpoints
# Protocol: beddel-declarative-protocol/v2.0
agent:
  id: filevine-guardian
  version: 1.0.0
  protocol: beddel-declarative-protocol/v2.0
metadata:
  name: "API Guardian Sentinel"
  description: "Protection against Broken Auth and Data Leakage"
  category: "security_middleware"
# LAYER 1: Input Validation (Input Hardening)
schema:
  input:
    type: "object"
    properties:
      method: { type: "string" }
      headers:
        type: "object"
        properties:
          authorization:
            type: "string"
            pattern: "^Bearer [a-zA-Z0-9-_.]+$"
        required: ["authorization"]
      body:
        type: "object"
        properties:
          projectName: { type: "string" }
    required: ["headers"]
# LAYER 2: Output Sanitization
  output:
    type: "object"
    properties:
      recommendations:
        type: "array"
        items:
          type: "string"
      requestId:
        type: "string"
    additionalProperties: false
logic:
  workflow:
    - name: "threat_scan_request"
      type: "security-threat-scan"
      action:
        vector: "brute_force"
        input: "$input.headers"
        weight: 0.5
    - name: "data_leak_inspection"
      type: "security-threat-scan"
      action:
        vector: "data_exfiltration"
        input: "$upstream_response"
        weight: 1.0

How would this have saved the day?

1. Blocking at Input (Broken Authentication)

In the original attack, Alex sent a request without tokens. With Beddel, the interpreter loads schema.input. Upon detecting the absence of the headers.authorization field (marked as required), the runtime triggers a DeclarativeSchemaValidationError immediately.

Result: The attack stops here with a 400 Bad Request or 401 Unauthorized. The vulnerable Filevine server is never even triggered.

2. Blocking at Output (Data Leakage)

Let's assume, hypothetically, that the attacker managed to bypass authentication (perhaps by stealing a valid session). The Filevine server would then process the request and return the fatal JSON containing the boxToken.
