CVE-2026-57073: Codechild Html::bare

Critical severity, CVSS 9.1. EPSS: 0.7% chance of exploitation in the next 30 days.

HTML::Bare versions through 0.04 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. Note that the latest version available on CPAN is version 0.02. Newer versions are available on the git repository.

Affected products

• Codechild Html::bare: up to and including 0.04
