DRUPAL-CONTRIB-2026-164

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.
