# CVE-2026-42202: nova-toggle-5: Improper authorization on toggle endpoint allowed non-Nova users to modify boolean fields

- Also known as: GHSA-F5C8-M5VW-RMGQ
- Severity: CVSS 6.5 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 1.3.0
- Published: 2026-05-08 · Updated: 2026-05-11

## Affected

- almirhodzic nova-toggle-5: fixed in 1.3.0
- almirhodzic/nova-toggle-5 (Packagist): fixed in 1.3.0

## Description

nova-toggle-5 enables fliping booleans in the index. Prior to version 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. This issue has been patched in version 1.3.0.

## What to do

- Check your stack: if you ship or depend on almirhodzic nova-toggle-5, almirhodzic/nova-toggle-5, upgrade to a fixed version (1.3.0) per the references below.
