Updated modules/processors/frame/core.py to fix security vulnerability [python.lang.security.audit.non-literal-import.non-literal-import]

[kira-offgrid]

Context and Purpose:

        This PR automatically remediates a security vulnerability:
        - **Description:** Untrusted user input in `importlib.import_module()` function allows an attacker to load arbitrary code. Avoid dynamic values in `importlib.import_module()` or use a whitelist to prevent running untrusted code.
        - **Rule ID:** python.lang.security.audit.non-literal-import.non-literal-import
        - **Severity:** MEDIUM
        - **File:** modules/processors/frame/core.py
        - **Lines Affected:** 23 - 23

        This change is necessary to protect the application from potential security risks associated with this vulnerability.

        **Solution Implemented:**

        The automated remediation process has applied the necessary changes to the affected code in `modules/processors/frame/core.py` to resolve the identified issue.

        Please review the changes to ensure they are correct and integrate as expected.

Summary by Sourcery

Mitigate a security vulnerability in dynamic module imports by enforcing a whitelist and replacing direct importlib calls with a safe import wrapper

Bug Fixes:

• Prevent arbitrary code loading via importlib.import_module by enforcing a whitelist for frame processor modules

Enhancements:

• Add ALLOWED_MODULES whitelist and safe_import_module function with logging for unauthorized import attempts
• Replace importlib.import_module usage in load_frame_processor_module with safe_import_module to enforce validation

Reviewer's Guide

This PR secures dynamic imports in modules/processors/frame/core.py by introducing a whitelist-driven safe_import_module function and replacing direct importlib.import_module calls with it; reviewers should also flag and consolidate redundant definitions.

File-Level Changes

Change	Details	Files
Introduced whitelist-based safe dynamic import mechanism	Imported typing Set and Optional Defined ALLOWED_MODULES set Implemented safe_import_module with whitelist check and warning log	modules/processors/frame/core.py
Replaced dynamic import usage with safe_import_module	Changed importlib.import_module call to safe_import_module in load_frame_processor_module	modules/processors/frame/core.py
Duplicated safe_import_module and whitelist definitions	Multiple identical blocks of ALLOWED_MODULES and safe_import_module were inserted Suggest consolidating to a single definition	modules/processors/frame/core.py
