FKIE_CVE-2026-13397

Vulnerability from fkie_nvd - Published: 2026-07-16 17:16 - Updated: 2026-07-17 14:17
Severity
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
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.
