Vulnerability from cvelistv5 – Published: 2026-06-09 22:40 – Updated: 2026-06-10 12:57

Title

SQLFluff: Uncontrolled Resource Consumption in Parser

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.

Severity

7.5 (High)

Vulnerability from github – Published: 2026-05-19 20:10 – Updated: 2026-07-06 22:53

Summary

SQLFluff: Uncontrolled Resource Consumption in SQLFluff Parser

Details

Impact

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.

Patches

Versions 4.2.0 and up contain a configurable parse node limit, which is enabled by default, to prevent this manner of exploit.

Credit

Ori Nakar from Imperva Threat Research Team.

Severity

7.5 (High)
