Overview
sqlfluffrs is a The SQL Linter for Humans
Affected versions of this package are vulnerable to Uncontrolled Recursion through the ParseContext and parser recursion in the SQL parser components. An attacker can exhaust parser stack depth and force repeated parse failures by supplying deeply nested SQL, such as long chains of brackets or other recursive grammar constructs. This can cause parsing to crash or stall, preventing users from linting or processing affected SQL inputs.
