How exploitable is this issue in practice?

Exploitability depends on how heavily a workflow trusts Fickling's classifications. If a system automatically deserializes pickles that are not marked OVERTLY_MALICIOUS, a crafted payload using `cProfile.run()` can realistically lead to arbitrary code execution.

What level of access does an attacker need?

An attacker must be able to supply or influence a pickle that will be analyzed by Fickling and later deserialized—this might be via file upload endpoints, artifact submission in CI, plugin ecosystems, or shared data exchanges between systems.

What is the safest general fix pattern?

Strengthen the analysis policy so that modules and APIs capable of executing arbitrary code, such as `cProfile`, are treated as unsafe by default, and update workflows so that non-affirmatively-safe classifications (SUSPICIOUS, unknown, or error) are not automatically allowed to proceed to deserialization.
