CVE-2026-13401  (opens in a new tab)

How to fix?

There is no fixed version for Echo:latest libxml-bare-perl.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libxml-bare-perl package and not the libxml-bare-perl package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

XML::Bare versions through 0.53 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.
