Drupal : vulnérabilité

1. Vérifier si vous êtes concerné

   Comparer la version installée aux versions corrigées ci-dessous.

   drush status --field=drupal-version
   composer show drupal/core

2. Corriger

   Versions corrigées : voir l'avis de l'éditeur (lien dans les sources).

   Mettre à jour le cœur ou le module concerné avec Composer, appliquer les mises à jour de base, vider les caches, sur chaque site.

   composer update "drupal/core-*" --with-all-dependencies
   composer update drupal/<module> --with-all-dependencies
   drush updatedb -y && drush cache:rebuild

3. En attendant le correctif

   Désactiver le module concerné (drush pm:uninstall <module>) si le correctif ne peut pas passer tout de suite, ou retirer la permission vulnérable aux rôles non administrateurs.

4. Contrôler

   drush status --field=drupal-version et composer show drupal/<module> doivent afficher la version corrigée.

PHP has announced a critical PHP security release for Wednesday, October 21, 2026, at 14:00 UTC. Reserve time to update PHP as soon as the release is available. If you manage PHP yourself, you’ll need to apply the update. If your host manages it, follow their communications for timing and any required action. Updating to a PHP release containing the patch to these vulnerabilities is the only complete mitigation. Site owners are responsible for maintaining the security of their hosting platform It is the policy of the Drupal Security Team that site owners are responsible for monitoring and maintaining the security of third-party libraries and any non-Drupal components of the application and hosting platform. In rare cases, the Drupal Security Team will post an informational public service announcement (PSA) such as this one, but the remit of the Drupal Security Team remains limited to code hosted on Drupal.org’s systems. Previous PSAs on third-party code in the Drupal ecosystem include: - External libraries and plugins - PSA-2011-002 - Various Third-Party Vulnerabilities - PSA-2019-09-04 - Third-Party Libraries and Supply Chains - PSA-2024-06-26 - Third-Party Libraries and Supply Chains - PSA-2025-09-17 This post is likely to be updated as the situation evolves and more information is available.
