CVE-2025-51481: Dagster Local File Inclusion vulnerability

Local File Inclusion in dagster._grpc.impl.get_notebook_data in Dagster 1.10.14 allows attackers with access to the gRPC server to read arbitrary files by supplying path traversal sequences in the notebook_path field of ExternalNotebookData requests, bypassing the intended extension-based check.

Root Cause Analysis

The vulnerability lies in the get_notebook_data function within dagster/_grpc/impl.py. The provided commit patch clearly shows the modification made to this function to fix a local file inclusion vulnerability. The original code used os.path.abspath on a user-provided path without proper validation, allowing an attacker to traverse the file system and read arbitrary files. The patch introduces a check to ensure that the requested file path is within the current working directory, thus preventing the path traversal attack. The commit message explicitly states that the purpose of the change is to fix a local file inclusion vulnerability in the ExternalNotebookData endpoint, which calls the get_notebook_data function. Therefore, dagster._grpc.impl.get_notebook_data is the vulnerable function.
