Vulnerability:
Access bypass
Affected versions:
<6.2.12 || >=6.3.0 <6.3.1
CVE IDs:
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.
Solution:
Install the latest version:
- If you use the 6.2.x branch of Webform upgrade to Webform 6.2.12.
- If you use the 6.3.x branch of Webform, upgrade to Webform 6.3.1.
