CVE-2026-114658 · Severity: high · CVSS 8.8 · Published 2026-10-22

The Grav Login plugin handles user account invitations and registration on Grav-based websites. A page author can craft an invitation form that grants super-user access, submit it without authentication, and create a super-user account, gaining full control of the site. This vulnerability bypasses access controls that should limit who can create privileged accounts.

<parameter name="attack_vector">["network"]

## Technical details

The login.invite task in the Login plugin fails to verify that the form submitter has authorization to create user accounts or grant privileges. The task reads the account access level directly from page frontmatter with no restrictions, allowing any unauthenticated visitor to submit the form and specify super-user privileges. An attacker with page-authoring permissions can define an invitation form in frontmatter that grants super access, and registration via a valid invitation token copies those privileges into the new account.

## Affected products

- Grav Login plugin 3.6.0 to 3.9.12
