Cpan · Net-Cidr-Lite · CVE-2026-45191
**Name of the Vulnerable Software and Affected Versions**
Net::CIDR::Lite versions prior to 0.24
**Description**
Improper validation of CIDR mask values allows extraneous zero characters to be processed. Mask forms such as "/00" and "/01" pass validation and are parsed as the same prefix as their unpadded equivalents, which may lead to an IP Access Control List (ACL) bypass.
**Recommendations**
Update to version 0.24 or later.
