Duplicate Advisory: Knowns Unrestricted Path Traversal leading to out-of-bounds arbitrary .md file read, write, and deletion in MCP Docs + Memory Tools
## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-9gfj-28hw-jchp. This link is maintained to preserve external references. ## Original Advisory knowns versions before 0.30.0 fail to validate filesystem paths in MCP tool arguments, allowing attackers to read, create, overwrite and delete files outside the project directory. Attackers can supply path arguments containing directory traversal sequences to access arbitrary Markdown files accessible to the server process.
