Problem
This line of code might contain a resource leak. Resource leaks can cause your system to slow down or crash.
Fix
Consider closing the following resource: pool. The resource is allocated by call multiprocessing.Pool. Execution paths that do not contain closure statements were detected. To prevent this resource leak, close pool in a try-finally block or declare it using a with statement.
More info

The rule flags the use of host 0.0.0.0 in application configuration, which exposes the server to all network interfaces, potentially including public networks. This configuration poses a security risk by making the application accessible to unauthorized users on the internet. To remediate this issue, bind your application to localhost 127.0.0.1 during development or use a specific, secure IP address in production environments with proper firewall rules and authentication mechanisms.Learn more

Enabling an application's debug or test feature makes it easier for developers to find bugs, but it also gives attackers access to detailed information about both the system running the application and users. To make your code secure, do not enable the debug or test feature on production servers. For more information, see CWE-489.

Potential NoSQL Injection detected. Untrusted input is being used in a NoSQL database
operation without proper sanitization. NoSQL databases like MongoDB and DynamoDB are not
immune to injection attacks. User input should never be directly interpolated into query
objects or strings. Instead, use parameterized queries, proper sanitization techniques,
or type conversion specific to the NoSQL database you're using. For MongoDB, consider using
ObjectId() for IDs and validated operators. For DynamoDB, use boto3.dynamodb.conditions
classes for safe query construction. Learn more - https://cwe.mitre.org/data/definitions/943.html
