Project: Browser Back Button [1]
Date: 2024-December-11
Security risk: *Moderately critical* 13 ∕ 25
AC:Basic/A:Admin/CI:Some/II:Some/E:Theoretical/TD:All [2]
Vulnerability: Cross site scripting

Affected versions: >=1.0.0 <2.0.2
Description: 
This module provides a block that renders a link providing the functionality
of a browser's back button.

The module does not sufficiently escape text entered by an administrator,
resulting in a cross scripting vulnerability.

This vulnerability is mitigated by the fact that an attacker must have a role
with the permission "administer blocks".

Solution: 
Install the latest version:

   * If you use the Browser Back Button module for Drupal 9.x/10.x, upgrade to
     Browser Back Button 2.0.2 [3]

   * Ivo Van Geertruyen [6] of the Drupal Security Team
