CVE-2026-57074: Codechild Xml::bare

Critical severity, CVSS 9.1. EPSS: 0.6% chance of exploitation in the next 30 days.

XML::Bare versions through 0.53 for Perl have an unbounded character lookahead. The parserc_parse function attempts to check for multicharacter strings such as "<![CDATA" or element terminators such as ">" without checking that the offsets are within the buffer. Truncated strings such as "<a/" can trigger an out-of-bounds read.

Affected products

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