Project: Webform [1]
Project machine name: webform
Date: 2026-September-23
Security risk: *Moderately critical* 13 ∕ 25
AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:Default [2]
Vulnerability: Access bypass, Server-side request forgery

Affected versions: <6.2.12 || >=6.3.0 <6.3.1
CVE IDs: CVE-2026-96370
Description: 
The Webform module allows site builders to create forms, collect submissions,
and configure access to forms and submission data.

The module includes a Webform Submission Export/Import submodule that allows
importing submission data from uploaded CSV files or remote URLs.

The submodule did not sufficiently validate access to export/import
functionality. A user who could edit webform submissions and access webform
results could also access the import interface, including the remote URL
import path, leading to a server-side request forgery vulnerability.

Sites that do not enable the Webform Submission Export/Import submodule are
not affected.

Solution: 
Install the latest version:

 * If you use the 6.2.x branch of Webform upgrade to Webform 6.2.12 [3].
 * If you use the 6.3.x branch of Webform, upgrade to Webform 6.3.1 [4].

For sites that need remote imports, explicitly configure the trusted hosts in
settings.php:

$settings['webform_submission_export_import_csv_hosts'] =
['staging.example.com'];
$settings['webform_submission_export_import_file_hosts'] =
['files.staging.example.com', '*.google.com'];
