CVE-2026-44717 Details
Description
MCP Calculate Server is a mathematical calculation service based on MCP protocol and SymPy library. Prior to 0.1.1, the use of eval() to evaluate mathematical expressions without proper input sanitization leads to remote code execution. This vulnerability is fixed in 0.1.1.
A remote code execution vulnerability exists in MCP Calculate Server versions prior to 0.1.1. The issue arises from the use of eval() to process mathematical expressions without adequate input sanitization, allowing arbitrary Python code execution. This vulnerability is particularly concerning as it can be exploited through prompt injection techniques, bypassing the application's only layer of security.
Users are advised to update to MCP Calculate Server version 0.1.1 or later. For those using earlier versions, it is recommended to implement strict input validation and sanitization before passing user-controlled input to eval(). Consider using a whitelist of allowed mathematical operations and symbols or explore alternative methods for safe mathematical expression evaluation.
