Arbitrary file overwrite via unvalidated statusFile path
Published May 1, 2026 · Updated May 1, 2026
Path traversal in Flux159 mcp-game-asset-gen 0.1.0 allows remote attackers to overwrite writable files through the MCP interface. The image_to_3d_async tool passes the client-controlled statusFile path to writeFileSync without validating that it remains in an output directory. Exploitation requires permission to invoke the tool, process write access to the selected path, and no filesystem sandbox; resulting JSON can corrupt files but does not expose their contents.
