What is CVE-2026-68578?

ArcadeDB versions prior to 26.7.3 exhibit a serious flaw in the MCP HTTP transport, where the authentication of the principal is not sufficiently enforced. This vulnerability enables users with non-root MCP permissions to bypass necessary permission checks, allowing them to execute arbitrary database operations, including schema mutations and JavaScript execution through the query tool. The lack of rigorous principal binding poses significant risks to data integrity and security.
