CVE-2026-7404 Details
Description
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. The project was informed of the problem early through an issue report but has not responded yet.
A relative path traversal vulnerability has been identified in Getsimpletool's Mcpo-Simple-Server, specifically in versions up to 0.2.0. The issue arises in the 'delete_shared_prompt' function within 'src/mcpo_simple_server/services/prompt_manager/base_manager.py'. The vulnerability allows remote attackers to manipulate the 'detail' argument, enabling unauthorized access to the filesystem by traversing directories and potentially reaching sensitive files or disrupting server operations.
It is recommended to restrict filesystem operations to a designated root directory, canonicalize and validate paths before use, and enforce boundary checks to prevent traversal attacks. Additionally, sensitive file operations should be limited to trusted, authenticated users.
