CVE-2026-5090 (2026-05-19)

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.

NAME

Template::Plugin::CGI - simple Template Plugin interface to CGI.pm module

SYNOPSIS

%% USE CGI %%
%% CGI.param('parameter') %%

%% USE things = CGI %%
%% things.param('name') %%

# see CGI docs for other methods provided by the CGI object

DESCRIPTION

This is a very simple Template Toolkit Plugin interface to the CGI module. A CGI object will be instantiated via the following directive:

%% USE CGI %%

CGI methods may then be called as follows:

%% CGI.header %%
%% CGI.param('parameter') %%

An alias can be used to provide an alternate name by which the object should be identified.

    %% USE mycgi = CGI %%
    %% mycgi.start_form %%
    %% mycgi.popup_menu({ Name   => 'Color'
			  Values => [ 'Green' 'Black' 'Brown' ] }) %%

Parenthesised parameters to the USE directive will be passed to the plugin constructor:

%% USE cgiprm = CGI('uid=abw&name=Andy+Wardley') %%
%% cgiprm.param('uid') %%
