Regex matching for SQL has no hard limits

    Details

      Description

      If one of the filters that uses a regular expression against an SQL statement is configured with a pattern that backtraces catastrophically and an excessively long SQL statement is used, the parsing can take several minutes. In order to protect against user errors, filters that use regular expressions could limit the length of the SQL statement to a default value. This would minimize the effects of expensive regular expressions.
