CVE-2026-114533 Drupal CVE debrief

A Drupal theme, agora_theme, provides a front-end design for transparency and open-government sites. The theme allows a table preview of CSV files attached to content but does not sufficiently check file access when rendering this preview. This can allow a visitor who can view the content but is refused download access to read the file's contents on the page. Additionally, a preview rendered for one visitor can be cached and shown to another. The vulnerability is mitigated if the site stores CSV files outside the public file system and restricts their download with an additional module or custom code. Files in the public file system are not affected.

Who should care

Drupal site administrators and security teams, especially those using the agora_theme and handling sensitive data in CSV files, should assess exposure and implement necessary controls to prevent unauthorized file content exposure.

Why it matters

CVE-2026-114533 allows unauthorized reading of CSV file contents on Drupal sites using the agora_theme due to insufficient file access checks. Defenders should verify exposure, especially for sites handling sensitive data, and implement proper file access controls and compensating measures.

  • Defenders need to verify exposure of Drupal sites using agora_theme and ensure proper file access controls.
  • Sites handling sensitive data in CSV files are at risk of unauthorized data exposure.
  • Successful exploitation can lead to reading of sensitive information without proper authorization.
  • Remediation priority is high for sites with sensitive data in CSV files.

Technical summary

The agora_theme for Drupal does not properly check file access when rendering previews of CSV files attached to content. This allows visitors who can view the content but not download the file to read its contents. The vulnerability is mitigated if CSV files are stored outside the public file system and download access is restricted with additional modules or custom code. Defenders should prioritize verifying exposure of Drupal sites using the agora_theme, especially those handling sensitive data in CSV files, and ensure proper file access controls are in place.

Defensive priority

Defenders should prioritize verifying exposure of Drupal sites using the agora_theme, especially those handling sensitive data in CSV files, and ensure proper file access controls are in place.

Recommended defensive actions

  • Verify if Drupal sites using agora_theme are exposed to this vulnerability, especially those handling sensitive data in CSV files.
  • Ensure that CSV files are stored outside the public file system and that download access is properly restricted with additional modules or custom code.
  • Review and update the theme to a version that addresses this vulnerability, if available.
  • Monitor for potential exploitation attempts and implement compensating controls as necessary.
  • Confirm whether affected Drupal sites 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.
