Summary

Details

sqlparse is a non-validating SQL parser module for Python. Prior to 0.6.0, groupcomments in sqlparse/engine/grouping.py repeatedly rescans comment-only statements before the MAXGROUPINGTOKENS guard, causing quadratic CPU consumption through sqlparse.parse() and sqlparse.format(sql, stripcomments=True). This issue is fixed in version 0.6.0.
