Integration data read and modification via unauthenticated handlers
Published Oct 3, 2025 · Updated Oct 3, 2025
Improper authentication in Anyquery 0.4.3 and earlier allows local users to read or alter integration data through its HTTP MCP server. The MCP handlers in controller/llm.go accepted listTables, describeTable, and executeQuery requests without checking an authorization token. Reachability requires access to the bound HTTP port, normally on localhost; bindings to 0.0.0.0 extend access subject to firewall rules.
