Miggo AIRoot Cause Analysis

The vulnerability stems from missing X-Frame-Options headers. The commit patching CVE-2022-3167 modified the CsrfAuth class in security.py to add 'X-Frame-Options: DENY' in a renamed _set_headers method (previously _set_same_site). The original _set_same_site function only handled cookie SameSite attributes but didn't implement frame restriction headers, making it the root cause. The addition of test_clickjacking_defense in test_csrf.py confirms the security header was missing in vulnerable versions.
