CVE-2026-55609— sublinear-time-solver: Arbitrary file write in consciousness-explorer / sublinear-time-solver MCP export_state

Quick assessment

Affected
ruvnet sublinear-time-solver
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

rUv sublinear-time-solver是rUv个人开发者的一个亚线性时间问题求解框架。 rUv sublinear-time-solver 1.6.0之前版本存在输入验证错误漏洞，该漏洞源于export_state和import_state工具将攻击者控制的filepath参数传递给文件系统操作，未限制目标或拒绝路径遍历，可能导致攻击者读取、写入或覆盖服务器进程可访问的任何文件，造成机密性和完整性损失及服务中断。

Vulnerability Title
sublinear-time-solver: Arbitrary file write in consciousness-explorer / sublinear-time-solver MCP export_state
Source: CVE Program / CVE List V5
Vulnerability Description
sublinear-time-solver is a Rust and WebAssembly library for solving asymmetric diagonally dominant systems in sublinear time. Prior to consciousness-explorer 1.1.2 and sublinear-time-solver 1.6.0, the export_state and import_state tools in src/consciousness-explorer/mcp/server.js pass the attacker-controlled filepath parameter to filesystem operations in src/consciousness-explorer/index.js without restricting the destination or rejecting traversal. The saveVectorToFile and loadVectorFromFile tools in src/mcp/server.ts contain the same sink class through the file_path parameter. An attacker able to invoke the MCP tools can read, write, or overwrite any file accessible to the server process, causing confidentiality and integrity loss and possible service disruption. This issue is fixed in consciousness-explorer 1.1.2 and sublinear-time-solver 1.6.0.
