Root Cause Analysis

The analysis of the security patch dbb064c2ddda74265b8174edd9775e1302ca6ba0 reveals a path traversal vulnerability in Dagster's log handling. The vulnerability originates in the get_captured_local_path method of the LocalComputeLogManager class, located in python_modules/dagster/dagster/_core/storage/local_compute_log_manager.py. The original implementation of this function used os.path.join to construct a file path from user-controlled input without adequate validation. This allowed an attacker to craft a request to the /logs endpoint with directory traversal sequences (e.g., .., URL-encoded as %2e%2e) to read sensitive files outside of the designated log storage directory. The provided patch confirms this by introducing a check that resolves the absolute path of the requested file and ensures it is located within the expected base directory, raising a ValueError if the check fails. The added unit tests also explicitly demonstrate the exploit vector. Therefore, the get_captured_local_path function is the direct source of the vulnerability.
