Fix and enhance Nuclei templates for real vulnerability detection
Major improvements: - Fixed all WebSocket OOB templates to use real WebSocket protocol instead of HTTP - Converted fake templates to actual vulnerability detection logic - Removed malicious/fake browser API templates - Enhanced config detection with proper secret pattern matching WebSocket fixes (5 templates): - websocket-upgrade-oob.yaml: Now uses websocket: protocol with real message inputs - websocket-subscription-oob.yaml: Tests subscription abuse via WebSocket messages - websocket-relay-oob.yaml: Tests message relay SSRF via actual WebSocket connections - websocket-origin-bypass-oob.yaml: Tests cross-origin validation with WebSocket headers - websocket-auth-bypass-oob.yaml: Tests auth bypass through WebSocket message flows New REAL templates added: - websocket-auth-bypass-real.yaml: Comprehensive WebSocket auth testing - tls-pqc-downgrade-attack.yaml: Real TLS downgrade detection (replaced fake PQC) - sensitive-config-exposure.yaml: High-confidence secret detection with entropy validation - dom-xss-detection.yaml: Browser-based XSS testing with headless protocol - web-cache-poisoning-real.yaml: Actual cache poisoning detection with verification - http3-quic-smuggling.yaml: HTTP/3 request smuggling detection - webauthn-passkey-bypass.yaml: WebAuthn protocol exploitation testing - brotli-compression-oracle-attack.yaml: BREACH-style compression attacks - php-config-backup-exposure.yaml: PHP backup file detection with credential matching Configuration improvements: - config-ini.yaml: Complete rewrite with INI format validation and secret patterns - Removed flow-basic-test.yaml and flow-ssl-simple.yaml (trivial/fake templates) All templates now: ✅ Use appropriate protocols (websocket:, headless:, ssl:) ✅ Test actual vulnerabilities, not just headers ✅ Include proper matchers and extractors ✅ Pass yamllint validation ✅ Follow ethical security testing practices 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>

Detects ACTUAL compression oracle vulnerabilities by injecting controlled
9+
data and measuring compression ratio differences. Tests BREACH-style attacks
10+
where user input is compressed with secrets, allowing secret extraction
11+
through compression ratio analysis.

Detects state confusion vulnerabilities in CHIPS (Cookies Having Independent

Partitioned State) implementations. Tests for cross-partition cookie leakage,

partition key bypass, and session fixation through partition manipulation.

This is bleeding-edge - almost no security research exists on CHIPS attacks.
