CVE-2026-96356
Description
The Webform module allows site builders to create forms, collect submissions, and configure access to forms and submission data. Webform did not sufficiently guard user-specific access rules against a malformed saved configuration. Under certain site-specific conditions, an access rule intended to grant submission access only to selected user accounts could also grant access to anonymous users. This vulnerability is mitigated by the fact that the bypass depends on malformed saved access-rule configuration.
