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".
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
