…rver.py - 1. Replaced open CORS/all-origins WebSocket with manual origin check against ALLOWED_ORIGINS. 2. Enforced API token in 'X-API-Token' header to prevent unauthorized connections. 3. Limited concurrent clients via MAX_CLIENTS. 4. Restricted message types (only ping/pong in this example). 5. Applied max_size and max_queue to guard against large frames. - Confidence: HIGH - Breaking changes: Yes
- 1. Added FRAME_RATE_LIMIT to throttle processing and prevent DoS by overloading CPU. 2. Introduced MAX_FRAME_WIDTH/HEIGHT checks to avoid memory exhaustion from huge frames. 3. Added TIMEOUT_SECONDS to limit overall run time. 4. Gracefully release camera resources. - Confidence: MEDIUM - Breaking changes: No
- 1. Replaced unbounded list with a deque(maxlen=MAX_HISTORY) to cap memory usage. 2. Added input type/shape validation on 'features'. 3. Guarded classify() to only run when sufficient history exists. - Confidence: HIGH - Breaking changes: No
…n_classifier.py - 1. Added validate_landmarks() to ensure correct length, structure, and numeric finiteness. 2. Raise error for malformed data to prevent downstream crashes. 3. Bounded temporal buffer at 10 frames. - Confidence: HIGH - Breaking changes: No
…tractor.py - 1. Enforced index bounds against REQUIRED_INDICES. 2. Validated landmarks is a list of length 33. 3. Checked each point has at least 2 coordinates and numeric types. 4. Clamped the cosine argument to avoid math domain errors. - Confidence: HIGH - Breaking changes: No
…eSimpleStats.js - 1. Wrapped JSON.parse in try/catch to handle corrupted/malicious data. 2. Whitelisted value types to only allow numbers. 3. Resets to empty object on parse failure. - Confidence: HIGH - Breaking changes: No
…ket/page.js - 1. Switched to wss:// and removed verbose debug logs. 2. Sent auth token as first message rather than exposing debug info. 3. Parsed JSON safely in onmessage and displayed only message type. - Confidence: MEDIUM - Breaking changes: No
…oseWebSocket.js - 1. Ensured wss:// usage. 2. Sent auth token in first message. 3. Wrapped JSON.parse in try/catch and performed minimal schema validation on incoming data. - Confidence: HIGH - Breaking changes: No
