Overview
sqlfluffrs is a The SQL Linter for Humans
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling through the Parser, ParseContext, and Rust parser match-tree handling in the parser components. An attacker can force excessive parse-tree growth by supplying unusually wide or expansive SQL that drives the parser to materialize an excessive number of nodes. This can exhaust CPU and memory during parsing and linting, causing the user’s SQL processing to stall or fail with an unhandled parse error.
