Details

SQLFluff is a modular SQL linter and auto-formatter with support for multiple dialects and templated code. Prior to version 4.2.0, in deployments where untrusted users can provide SQL queries to be linted, an untrusted user can submit a malicious long query to any application using the parser to trigger a Denial of Service through resource exhaustion. This issue has been patched in version 4.2.0.
