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::Simple - pure Perl 5 template engine for Dancer

VERSION

version 1.3522

DESCRIPTION

This template engine is provided as a default one for the Dancer micro framework.

This template engine should be fine for development purposes but is not a powerful one, it's written in pure Perl and has no C bindings to accelerate the template processing.

If you want to power an application with Dancer in production environment, it's strongly advised to switch to Dancer::Template::TemplateToolkit.

SYNTAX

A template written for Dancer::Template::Simple should be working just fine with Dancer::Template::TemplateToolkit. The opposite is not true though.

variables

To interpolate a variable in the template, use the following syntax:

<% var1 %>

If 'var1' exists in the tokens hash given, its value will be written there.
