CVE-2026-13397

HIGH

HTML::Bare versions through 0.04 for Perl will hang in an infinite loop when parsing malformed attributes

Title source: cna
STIX 2.1

Description

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