### Impact

Similar to [another advisory](https://github.com/statamic/cms/security/advisories/GHSA-72hg-5wr5-rmfc), certain additional PHP files crafted to look like images may be uploaded regardless of mime type validation rules. This affects front-end forms using the "Forms" feature, and asset upload fields in the control panel.
