Security Advisories (3)
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.

NAME

XML::LibXML::DocumentFragment - DOM L2 Implementation of a Document Fragment

DESCRIPTION

This class is a helper class as described in the DOM Level 2 Specification. It is implamented as a node without name. All adding, inserting or replacing functions are aware about document fragments now.

As well all unbound nodes (all nodes that does not belong to any document subtree) are implicit member of document fragments. =back
