CVE-2023-36830

Summary

CVE-2023-36830 affects SQLFluff, an SQL linting tool, before version 2.1.2. This vulnerability allows untrusted users with access to config files to execute arbitrary Python code via macros using the `library_path` config value. The risk is higher in larger user bases or when SQLFluff is bundled with other tools where developers wish to give users config customization. The 2.1.2 release introduces the `--library-path` option, which overrides `library_path` values from config files and effectively prevents the attack. Users can also disable the `library-path` option entirely using `--library-path none`. Validating or limiting access to configuration files is a workaround that does not require an upgrade.
