CVE-2026-114535 Drupal CVE debrief

Who should care

Drupal site administrators, security teams, and developers who use the Swiper module should assess exposure and take necessary actions to protect their sites. They should verify access controls for content entities displayed in dialogs, check for updates and apply patches or upgrades as necessary, and monitor field-level access controls for potential bypasses.

Why it matters

This vulnerability affects Drupal sites using the Swiper module, allowing potential access control bypasses. Site administrators and security teams should assess exposure and take necessary actions to protect their sites.

• Verify access controls for content entities displayed in dialogs
• Check for updates and apply patches or upgrades as necessary
• Monitor field-level access controls for potential bypasses

Technical summary

The Swiper module for Drupal provides a route for displaying published content entities in a dialog. However, the route does not sufficiently verify the current user's access to the specific entity. This vulnerability is mitigated by the fact that only rendered output is returned, and field-level access controls are still enforced. The affected versions are <2.1.2 and >=3.0.1 <3.1.0. The vulnerability affects Drupal sites using the Swiper module, potentially allowing access control bypasses. Site administrators and security teams should assess exposure and verify if their sites use the affected versions of the Swiper module.

Defensive priority

Drupal site administrators and security teams should assess exposure and verify if their sites use the affected versions of the Swiper module. They should check for updates and apply patches or upgrades as necessary.

Recommended defensive actions

• Assess exposure by checking if the site uses affected versions of the Swiper module
• Verify field-level access controls are in place and functioning correctly
• Monitor for updates and apply patches or upgrades as necessary
• Review and adjust access controls for content entities displayed in dialogs
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
