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::Session::Simple - in-memory session backend for Dancer

VERSION

version 1.3522

DESCRIPTION

This module implements a very simple session backend, holding all session data in memory. This means that sessions are volatile, and no longer exist when the process exits. This module is likely to be most useful for testing purposes.

CONFIGURATION

The setting session should be set to Simple in order to use this session engine in a Dancer application.
