CVE-2026-57073

CRITICAL

Description

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.
