CVE-2026-15043— DBI::SQL::Nano versions from 1.42 before 1.651 for Perl have inverted <= and >= SQL operators on text

Quick assessment

Affected
HMBRAND DBI::SQL::Nano
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Perl dbi是Perl组织开源的一种数据库接口模块。 Perl dbi 1.42版本至1.651之前版本存在处理逻辑错误漏洞，该漏洞源于在is_matched方法的非数字字符串分支中，<=和>= SQL运算符被错误反转，使用Perl的ge和le运算符进行评估，可能导致依赖WHERE子句过滤数据的应用程序返回错误行。

DBI::SQL::Nano versions from 1.42 before 1.651 for Perl have inverted <= and >= SQL operators on text
Source: CVE Program / CVE List V5
Vulnerability Description
DBI::SQL::Nano versions from 1.42 before 1.651 for Perl have inverted <= and >= SQL operators on text. DBI::SQL::Nano, DBI's built-in mini-SQL engine, evaluated WHERE predicates incorrectly in some cases. In the non-numeric string branch of the is_matched method, <= was evaluated using Perl's ge operator, and >= was evaluated using Perl's le operator. SQL::Nano is the fallback query engine for DBI's 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 <=/>= comparison silently returns the wrong rows.
