A security issue was found in Nuxt Image and the ipx library it uses. Appwrite Cloud now blocks some of the related requests to Sites at the firewall. This is extra protection only. It does not replace an upgrade.
If you run a Nuxt site, update @nuxt/image to 1.11.2 or 2.2.1, or ipx to 2.1.2, 3.1.3, or 4.1.0, then create a new deployment.
Self-hosted Appwrite does not get this firewall change. Update the same packages in the site and redeploy.
