Name of the Vulnerable Software and Affected Versions Data::Validate::IP versions 0.29 and earlier

Description The issue is related to improper authorization in the Data::Validate::IP module. It allows a remote attacker to impact data integrity by bypassing access control based on IP addresses. This is due to the module not properly considering extraneous zero characters at the beginning of an IP address string.

Recommendations For versions 0.29 and earlier, consider updating to a version that properly handles IP address strings to prevent access control bypass. As a temporary workaround, restrict the use of the Data::Validate::IP module until a patch is available.
