CVE-2026-13401: Codechild Xml::bare

High severity, CVSS 7.5. EPSS: 0.4% chance of exploitation in the next 30 days.

XML::Bare versions through 0.53 for Perl will hang in an infinite loop when parsing malformed attributes. The parserc_parse function never advances the attribute-parse state cursor on certain malformed attribute forms, looping forever. Nameless attributes such as "<a ='c'>" or unbalanced quotes "<a b='''''''c'>" can trigger this condition.

Affected products

• Codechild Xml::bare: up to and including 0.53
