======================================================================== CVE-2026-13397 CPAN Security Group ======================================================================== CVE ID: CVE-2026-13397 Distribution: HTML-Bare Versions: through 0.04 MetaCPAN: https://metacpan.org/dist/HTML-Bare VCS Repo: https://github.com/nanoscopic/perl-HTML-Bare HTML::Bare versions through 0.04 for Perl will hang in an infinite loop when parsing malformed attributes 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. Problem types ------------- - CWE-835 Loop with Unreachable Exit Condition ('Infinite Loop') Workarounds ----------- Apply the patch.
