CVE-2026-8177

A flaw was found in XML::LibXML for Perl. A remote attacker could exploit this vulnerability when processing specially crafted XML node names containing incomplete UTF-8 character sequences. This can lead to an out-of-bounds read in heap memory, potentially causing the application to crash and resulting in a denial of service.
