  "title": "DBI::SQL::Nano versions from 1.42 before 1.651 for Perl have inverted \u003C= and \u003E= SQL operators on text",
  "description": "DBI::SQL::Nano versions from 1.42 before 1.651 for Perl have inverted \u003C= and \u003E= SQL operators on text.  DBI::SQL::Nano, DBI\u0027s built-in mini-SQL engine, evaluated WHERE predicates incorrectly in some cases. In the non-numeric string branch of the is_matched method, \u003C= was evaluated using Perl\u0027s ge operator, and \u003E= was evaluated using Perl\u0027s le operator.  SQL::Nano is the fallback query engine for DBI\u0027s file-backed drivers (DBD::File, DBD::DBM, CSV-style drivers) whenever SQL::Statement is not installed, and is forced whenever DBI_SQL_NANO=1. Queries over such tables use these predicates directly.  The impact depends on the context. Where an application relies on a WHERE clause to filter file-backed data for policy or authorization, an inverted \u003C=/\u003E= comparison silently returns the wrong rows.",
