Drupal core - Moderately critical - Information Disclosure - SA-CORE-2023-003

Project:       Drupal core

Date:          2023-March-15

Security risk: Moderately critical 13â\x{136}\x{149}25

Vulnerability: Information DisclosureAffected versions:
>=8.0.0 <9.4.12 || >=9.5.0 <9.5.5 || >=10.0.0 <10.0.5

The language module provides a Language switcher block which can be placed to
provide links to quickly switch between different languages.

The URL of unpublished translations may be disclosed. When used in conjunction
with a module like Pathauto, this may reveal the title of unpublished content.

This advisory is not covered by Drupal Steward .


Install the latest version:

  o If you are using Drupal 10.0, update to Drupal 10.0.5 .
  o If you are using Drupal 9.5, update to Drupal 9.5.5 .
  o If you are using Drupal 9.4, update to Drupal 9.4.12 .

All versions of Drupal 9 prior to 9.4.x are end-of-life and do not receive
security coverage. Note that Drupal 8 has reached its end of life .

Drupal 7 core does not include the Language module and therefore is not
affected. The contributed modules for translation do not have the same code for
language-switching links, so they are not affected, either.
