Official description

Redash is a package for data visualization and sharing. From 10.0.0 until 26.9.0, the JSON data source query runner in redash/query_runner/json_ds.py used _get_all_results() to combine its configured base_url with a user-supplied query URL by using urljoin. An absolute query URL replaced the configured base URL instead of remaining under it, allowing a user with execute_query permission to direct a server-side request to an arbitrary external origin. When HTTP Basic Auth was configured for the data source, the request also forwarded those credentials to the selected origin. Private and internal address access remained constrained when REDASH_ENFORCE_PRIVATE_IP_BLOCK was enabled. This issue is fixed in version 26.9.0.
