CVE-2026-55609
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.
What this means for your business
- An attacker can use it only with access to the machine itself, with an ordinary user login, and without anyone at your company clicking anything.
- FIRST's prediction model gives it a 0.1% chance of attack attempts being seen in the next 30 days, ranking above 1% of all known flaws.
What to do
- 1Ask your IT team or provider whether any of your systems use the affected product.
- 2If you do, follow the vendor's guidance. No patch reference has been published yet.
