CVE-2026-96373

The Webform module allows site builders to create forms, collect submissions, and configure access to forms and submission data.

The module does not sufficiently validate requested filenames when serving generated submission exports. Under certain configurations, a user with permission to view submission results for one webform may be able to access or remove files from the configured export temporary directory that were not generated for that webform.

This vulnerability is mitigated by the fact that an attacker must have access to view submission results for a webform and must know or be able to determine a target filename.
