CVE-2015-3451 (2015-04-23)

The _clone function does not properly set the expand_entities option, which allows remote attackers to conduct XML external entity (XXE) attacks via crafted XML data to the (1) new or (2) load_xml function.

CVE-2017-10672 (2015-04-23)

Use-after-free in the XML-LibXML module through 2.0129 for Perl allows remote attackers to execute arbitrary code by controlling the arguments to a replaceChild call.

CVE-2026-8177 (2026-05-10)

XML::LibXML versions through 2.0210 for Perl read out-of-bounds heap memory when parsing XML node names containing truncated UTF-8 byte sequences. A node name ending in the middle of a multi byte UTF-8 sequence causes the parser to read past the end of the input string into adjacent heap memory. Any Perl process that passes attacker controlled strings to XML::LibXML's DOM node-name methods can reach this path on the default API. The likely consequence is a crash, causing denial of service.
