CVE-2026-7384 Details
Description
A vulnerability was detected in ezequiroga mcp-bases 357ca19c7a49a9b9cb2ef639b366f03aba8bea39/c630b8ab0f970614d42da8e566e9c0d15a16414c. This impacts the function search_papers of the file research_server.py. Performing a manipulation of the argument topic results in path traversal. Remote exploitation of the attack is possible. The exploit is now public and may be used. This product follows a rolling release approach for continuous delivery, so version details for affected or updated releases are not provided. The project was informed of the problem early through an issue report but has not responded yet.
A path traversal vulnerability has been identified in Ezequiroga MCP-Bases, specifically in the 'search_papers' function of 'research_server.py'. This vulnerability allows for remote exploitation by manipulating the 'topic' argument, leading to unauthorized file access and modification. The issue arises because the application fails to properly sanitize the 'topic' input before using it to create directories and files, enabling attackers to traverse the file system and write to arbitrary locations.
To address this vulnerability, the application should reject 'topic' values that contain path traversal tokens or absolute-path syntax. Implementing proper path canonicalization before creating directories or opening files can prevent exploitation. Additionally, consider using a server-generated identifier for storage directories instead of raw topic strings.
