Local filesystem disclosure via unused path validator
Published Jul 13, 2026 · Updated Jul 13, 2026
Path validation bypass in Lama Al Rajih KiCad MCP Server 3.3.0 through 3.3.1 allows local users to enumerate process-readable paths. Fifteen MCP tool handlers pass caller-controlled project_path or schematic_path values directly to filesystem APIs without invoking the shipped PathValidator. An attacker must be able to invoke the local MCP server, and the resulting disclosure is limited to path reachability, matching directory entries, and short parser-error prefixes rather than complete arbitrary file contents.
