CVE-2026-46374 Details
Description
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.
A denial-of-service vulnerability has been identified in SQLFluff versions prior to 4.2.0. In environments where untrusted users can submit SQL queries for linting, a malicious user could send a long, harmful query that exhausts system resources, causing the application to slow down or become unresponsive.
Users can upgrade to SQLFluff version 4.2.0 or later, which includes a default configurable parse node limit to prevent this type of resource exhaustion.
