Affected: Ubuntu:16.04:LTS: libtemplate-perl, Ubuntu:18.04:LTS: libtemplate-perl, Ubuntu:20.04:LTS: libtemplate-perl, Ubuntu:22.04:LTS: libtemplate-perl, Ubuntu:24.04:LTS: libtemplate-perl, Ubuntu:25.10: libtemplate-perl, Ubuntu:26.04:LTS: libtemplate-perl

Template::Plugin::HTML versions before 3.103 for Perl allows HTML and JavaScript to be injected. The html_filter function did not escape single quotes. HTML attributes inside of single quotes could be have code injected. For example, the variable "var" in <a id='ref' title='[% var | html %]'> would not be properly escaped. An attacker could insert some limited HTML and JavaScript, for example, var = " ' onclick='while (true) { alert(1) }'" Note that arbitrary HTML and JavaScript would be difficult to inject, because angle brackets, ampersands and double-quotes would still be escaped.
