Security Advisories (1)
CVE-2026-5080 (2026-04-30)

Dancer::Session::Abstract versions through 1.3522 for Perl generates session ids insecurely. The session id is generated from summing the character codepoints of the absolute pathname with the process id, the epoch time and calls to the built-in rand() function to return a number between 0 and 999-billion, and concatenating that result three times. The path name might be known or guessed by an attacker, especially for applications known to be written using Dancer with standard installation locations. The epoch time can be guessed by an attacker, and may be leaked in the HTTP header. The process id comes from a small set of numbers, and workers may have sequential process ids. The built-in rand() function is seeded with 32-bits and is considered unsuitable for security applications. Predictable session ids could allow an attacker to gain access to systems.

NAME

Dancer::Template - template wrapper for Dancer

VERSION

version 1.3522

DESCRIPTION

This module is the wrapper that provides support for different template engines.

USAGE

Default engine

The default engine used by Dancer::Template is Dancer::Template::Simple. If you want to change the engine used, you have to edit the template configuration variable.

Configuration

The template configuration variable tells Dancer which engine to use for rendering views.

You change it either in your config.yml file:

# setting TT as the template engine
template: "template_toolkit"

Or in the application code:

# setting TT as the template engine
set template => 'template_toolkit';
