Title

getsimpletool mcpo-simple-server base_manager.py delete_shared_prompt path traversal

Summary

A weakness has been identified in getsimpletool mcpo-simple-server up to 0.2.0. Affected is the function delete_shared_prompt of the file src/mcpo_simple_server/services/prompt_manager/base_manager.py. This manipulation of the argument detail causes relative path traversal. It is possible to initiate the attack remotely. The exploit has been made available to the public and could be used for attacks.
