Advisories for Pypi/Code-Graph-Rag package

The read_file MCP tool in codebase_rag/mcp/tools.py contains a path traversal vulnerability in its paginated branch (when offset or limit is supplied). The handler constructs a file path using Path(self.project_root) / file_path without subsequently validating that the resolved path remains within the configured project root. Python's pathlib silently discards the left-hand component when the right-hand argument is an absolute path, allowing an attacker to read any UTF-8-readable file on the server …

A remote/local attacker who can get a symbolic link included in a source-code repository that code-graph-rag analyzes can cause the structural_search and structural_replace tools (backed by AstGrepService, exposed both as MCP tools and as agentic AI tools) to read and – via structural_replace with dry_run=False – overwrite arbitrary files outside the configured project root, because the tool's path-containment check (should_skip_path/_classify_file) is performed lexically on the unresolved path and never checks …
