[samay2504]

fixes #2074

Proposed Fix

Replace bare except: with explicit except Exception::

except Exception:
    if logger:
        logger(
            f"Failed to create VulnerabilitySeverity for: {severity} with error:\n{traceback_format_exc()}",
            level=logging.ERROR,
        )

Detection Method

Found using ruff check . --select=E722 which reported 6 bare except violations in the codebase.
