Risk Assessment

A remote attacker could exploit path traversal to write or read files outside the intended directory, potentially leading to file overwrite or data leakage. The lack of version details complicates patch management.

Recommendation

Update the project to the latest available version or implement validation of the outputFile argument and restrict filesystem access. Monitor API traffic for path traversal attempts.
