Summary
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.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
