This playbook provides structured checklists and proof-of-concept templates to efficiently uncover these overlooked risks.

Standard automated security scanning fails to detect modern CSRF risks because it often overlooks complex bypass vectors like SameSite Lax/Strict bypasses, JSON CSRF, and OAuth state parameter flaws. This playbook addresses these gaps with specialized testing guidance.
