42Crunch for Framework version upgrade audit

When upgrading framework versions, API interfaces often shift in subtle ways that are hard to detect with generic tests. Parameter names, response shapes, and security requirements can change between versions while documentation lags. These drifts create surface area for misconfiguration and exposure. Evaluations must focus on contract compatibility and security posture rather than simple availability checks.

Findings align with PCI-DSS 4.0, SOC 2 Type II, and OWASP API Top 10 (2023). For PCI-DSS 4.0, detection of authentication bypass and data exposure maps to requirements around access control and cardholder data protection. For SOC 2 Type II, scan coverage supports evidence collection for system security and availability controls. OWASP API Top 10 (2023) coverage spans broken authentication, excessive data exposure, and security misconfiguration categories. For other frameworks, middleBrick helps you prepare for audits by surfacing findings relevant to security controls described in HIPAA, GDPR, ISO 27001, NIST, CCPA, and similar regimes without asserting certification or compliance guarantees.

Because no agents or SDKs are installed, the scanner works against any running API endpoint regardless of language or hosting model. It verifies contract stability by probing defined routes and observing responses. Authentication schemes such as Bearer, API key, Basic auth, and Cookie-based sessions are supported under authenticated scanning where domain ownership is verified. Only whitelisted headers are forwarded, ensuring probe traffic remains controlled and predictable during upgrade assessment.

The scanner reviews twelve categories tied to OWASP API Top 10 (2023), which are valuable when assessing framework upgrades. Detection areas include authentication misconfigurations, broken object level authorization, excessive property exposure, input validation gaps, rate limiting behavior, data exposure such as PII and API key leakage, encryption settings, SSRF indicators, inventory and versioning issues, and unsafe consumption patterns. For LLM-facing endpoints, adversarial probe coverage spans prompt extraction, jailbreak attempts, and token smuggling across multiple scan tiers.

Provide a URL or OpenAPI specification to initiate a scan. The system resolves recursive $ref entries and compares spec definitions against observed runtime behavior, highlighting undefined security schemes, deprecated operations, and missing pagination. Results are delivered through a web dashboard with trend tracking, downloadable compliance PDFs, and an npm CLI for scripting. A GitHub Action can gate CI/CD pipelines based on score thresholds, and an MCP server enables scanning from AI-assisted development tools. Pro tier adds scheduled rescans, diff detection, email alerts, signed webhooks, and enterprise features such as SSO and audit logs.
