"details": "### Impact\n\nIn deployments where untrusted users can provide SQL queries to be linted, an untrusted user can submit a malicious query with deliberate excessive nesting to any application using the parser to trigger a Denial of Service through resource exhaustion.\n\n### Patches\n\nVersions 4.1.0 and up contain a configurable recursion limit, which is enabled by default, to prevent this manner of exploit.\n\n### Credit\n\nOri Nakar from Imperva Threat Research Team.",
