# SKILL: SAML SSO and Assertion Attacks — Signature Validation, Binding, and Trust Confusion
> **AI LOAD INSTRUCTION**: Use this skill when the target uses SAML-based SSO and you need to validate assertion trust: signature coverage, audience and recipient checks, ACS handling, XML parsing weaknesses, and IdP/SP confusion.
## 1. WHEN TO LOAD THIS SKILL
Load when:
- Enterprise SSO uses SAML requests or responses
- You see `SAMLRequest`, `SAMLResponse`, XML assertions, or ACS endpoints
- Login flows involve an external IdP and browser POST/redirect binding
## 2. HIGH-VALUE MISCONFIGURATION CHECKS
