nova-toggle-5: Improper authorization on toggle endpoint allowed non-Nova users to modify boolean fields

Moderate severity GitHub Reviewed Published Apr 20, 2026 in almirhodzic/nova-toggle-5 • Updated May 13, 2026

Package

Affected versions

< 1.3.0

Patched versions

1.3.0

Description

Impact

In versions < 1.3.0, the toggle endpoint (POST /nova-vendor/nova-toggle/toggle/{resource}/{resourceId}) was protected only by web + auth:<guard> middleware. Any user authenticated on the configured guard could call the endpoint and flip boolean attributes on any Nova resource — including users who do not have access to Nova itself (for example, frontend customers sharing the web guard with the Nova admin area).

The endpoint also accepted an arbitrary attribute parameter, which meant a valid caller could toggle any boolean column on the underlying model — not just columns exposed as Toggle fields on the resource.

Patches

Fixed in 1.3.0:

  • The route is now protected by Nova's nova:api middleware, which enforces the viewNova gate.
  • The controller now checks the resource's authorizedToUpdate policy.
  • The controller only accepts attributes that are declared as a Toggle field on the resource and are not readonly in the current request context.

Workarounds

Users who cannot upgrade immediately can either remove the package or restrict access to the /nova-vendor/nova-toggle/toggle/* routes via an additional middleware in their application that enforces the viewNova gate.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
