CVE-2026-45190

Name of the Vulnerable Software and Affected Versions Net::CIDR::Lite versions prior to 0.24

Description Net::CIDR::Lite for Perl fails to properly validate IP address and CIDR mask inputs. Inputs containing non-ASCII digit characters or a trailing newline pass validation but are re-encoded by the parser into an address different from the original input string. This can cause the find() and bin find() functions to incorrectly match or miss addresses, potentially leading to an IP Access Control List (ACL) bypass.

Recommendations Update to version 0.24 or later.
