ADDED Requirements
Requirement: Input Length Validation
The system SHALL enforce maximum length limits on all user-provided string inputs to prevent DoS attacks and database overflow.
Scenario: Task title exceeds maximum length
- WHEN user submits a task with title longer than 500 characters
- THEN system returns 422 Validation Error with descriptive message
Scenario: Description field within limits
- WHEN user submits content with description under 10000 characters
- THEN system accepts the input and processes normally
Requirement: Secure WebSocket Authentication
The system SHALL authenticate WebSocket connections without exposing tokens in URL query parameters.
Scenario: WebSocket connection with token in first message
- WHEN client connects to WebSocket endpoint
- THEN server waits for authentication message containing JWT token
- THEN server validates token before accepting further messages
Scenario: WebSocket connection timeout without authentication
- WHEN client connects but does not send authentication within 10 seconds
- THEN server closes the connection with appropriate error code
Requirement: Path Traversal Protection
The system SHALL prevent file path traversal attacks by validating all file paths resolve within the designated storage directory.
Scenario: Path traversal attempt detected
- WHEN request contains file path with "../" or absolute path outside storage
- THEN system rejects request and logs security warning
- THEN system returns 403 Forbidden error
Scenario: Valid file path within storage
- WHEN request contains valid relative file path
- THEN system resolves path and verifies it is within storage directory
- THEN system processes file operation normally
