Object.prototype. Every downstream object inherits the malicious values, enabling auth bypass and RCE. Fix: Object.create(null) and schema validation on all untrusted payloads.helmet middleware: enforces HSTS (downgrade prevention), CSP (XSS mitigation), X-Frame-Options: DENY (clickjacking). Disable x-powered-by header to suppress server fingerprinting.req.body passed to MongoDB allows $gt operator abuse to bypass password checks entirely. Sanitize all payloads with express-mongo-sanitize before ORM operations.npm audit in every CI/CD pipeline. Use npm ci for deterministic builds. Block post-install scripts with --ignore-scripts to prevent malicious package hooks.== operator casts types before comparison. "Magic hash" strings such as 0e1234 evaluate to 0, enabling authentication bypass without knowledge of the real password. Mitigation: strict === comparison in all authentication logic.&is_admin=true to a profile update request writes the column if unprotected. Fix: enforce strict $fillable allowlists — never use $guarded = [] in production.session.cookie_httponly=1 (block JS access), session.cookie_secure=1 (TLS-only transmission), and session.use_strict_mode=1 (prevent Session Fixation attacks).finfo_file(). Strip EXIF metadata to prevent data leakage. Store uploads outside public_html — direct-access webshell RCE is the critical failure mode when this is skipped.context.WithCancel and always close channels explicitly. Detect leaks in CI with the goleak testing library before they reach production.go test -race in CI. Enforce safe access patterns via sync.Mutex or channel-based communication.database/sql parameterized queries — never fmt.Sprintf for SQL construction. For templates, use html/template (context-aware auto-escaping) over text/template to prevent XSS in generated output.crypto/rand over predictable math/rand. Use golang.org/x/crypto/bcrypt for credential storage. Implement AES-GCM via crypto/cipher for authenticated encryption — provides both confidentiality and integrity.ReadTimeout, WriteTimeout, and IdleTimeout on the http.Server struct. This prevents Slowloris DoS by forcibly closing stalled connections that attackers use to exhaust server threads.govulncheck maps CVEs to specific imported functions in the compiled binary — not just declared dependencies. gosec performs AST-based analysis for hardcoded credentials. golangci-lint enforces idiomatic error handling across the entire CI/CD pipeline.govulncheck provide binary-level CVE attribution — a significant advantage over dependency-manifest-only scanners used in other ecosystems.unsafe blocks. Rust cannot verify external memory safety. The majority of Rust CVEs in the ecosystem originate at FFI boundaries. Audit all unsafe blocks with miri for undefined behavior detection before merging to main.rustls — memory-safe, no OpenSSL C-bindings required.RustCrypto for hashing and block ciphers, ring for AEAD (authenticated encryption), rustls for TLS termination. Each eliminates a C-binding FFI attack surface.cargo audit — CVE scanning against advisory database. cargo deny — bans vulnerable crates and enforces license compliance policies. cargo vet — requires manual audit attestation before a crate can be compiled into the binary.cargo fuzz with libFuzzer bombards APIs with malformed inputs to find panics and undefined behavior. miri detects strict-aliasing violations and UB during test execution — essential for all unsafe block validation.pickle.loads() executes arbitrary functions defined in __reduce__. Loading any untrusted pickle file equals immediate remote code execution. Replace with json, msgpack, or ast.literal_eval() for safe data parsing. Maps to OWASP A08:2021 — Software and Data Integrity Failures.{{ config.items() }} to leak secrets or traverse the MRO chain for RCE. Always pass data as context variables — never concatenate user input into template strings.CsrfViewMiddleware. Use ORM parameterized queries natively. Set SECURE_SSL_REDIRECT=True, SESSION_COOKIE_SECURE=True, X_FRAME_OPTIONS='DENY' in production settings.Flask-Talisman enforces secure HTTP headers across all routes. FastAPI's Pydantic models enforce strict type hints, value boundaries, and regex patterns on all JSON payloads — neutralizing malformed data attacks at the framework layer before business logic executes.requets vs requests) and dependency confusion attacks targeting private package names. Pin hashes in requirements.txt. Use private PyPI mirrors on Cyber IaaS for air-gapped environments requiring controlled package ingestion.
gosec, clippy, cargo fuzz), runtime hardening (helmet, Flask-Talisman, Axum extractors), and dependency scanning (govulncheck, cargo audit) map to ADG's 9 Governance Surfaces.
