CVE-2026-45191 is fixed in 2 products on 1 platform, first by ALAS2023-2026-1732, released May 25, 2026. It is not reported as exploited. Patch Radar priority: Routine.
Net::CIDR::Lite versions before 0.24 for Perl does not properly consider extraneous zero characters in CIDR mask values, which may allow IP ACL bypass. Mask forms like "/00" and "/01" pass validation and parse to the same prefix as their unpadded value. See also CVE-2026-45190.
