Hi,
The following vulnerability was published for libtemplate-perl.
CVE-2026-5090[0]:
| Template::Plugin::HTML versions through 3.102 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.
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
