high Legacy software ssrf conf 1.00 [SEC029] Server-Side Request Forgery (SSRF) — outbound HTTP from user input: Outbound HTTP request to a user-controlled URL without allowlist validation. Attackers can probe internal services (169.254.169.254 metadata, internal Kubernetes endpoints, file:// URIs), exfiltrate data, or pivot through your network. SSRF is OWASP A10:2021 and a frequent foothold in cloud breaches.
Validate the URL against an allowlist BEFORE fetching: ALLOWED = {'images.example.com', 'cdn.example.com'} host = urlparse(url).hostname if host not in ALLOWED: abort(400) Or use a server-side proxy (Imgproxy / serve-files-only-from-S3) that isolates outbound network access from the request h…

high Legacy software resource_exhaustion conf 1.00 [SEC035] Unbounded Resource Allocation — DoS risk: Allocating resources (buffers, recursion stack, large ranges) based on user input without an upper bound. Attackers send `size=10000000` to exhaust memory, or trigger expensive computation. CWE-770/400. Examples: CVE-2023-44487 (HTTP/2 Rapid Reset), countless YAML/XML billion-laughs variants.
Cap user-controlled sizes BEFORE allocation: size = min(int(request.args.get('n', 100)), MAX_SIZE) Set framework-level limits: Flask: app.config['MAX_CONTENT_LENGTH'] = 10 * 1024 * 1024 FastAPI: use middleware to enforce request size Django: DATA_UPLOAD_MAX_MEMORY_SIZE in settings.py …
