CVE-2023-28104
HIGH7.5EPSS 0.31%DDOS attack on graphql endpoints
Published: 3/16/2023Modified: 11/8/2023
Also known as:GHSA-67g8-c724-8mp3
Description
An attacker could use a specially crafted graphql query to execute a Distributed Denial of Service attack (DDOS attack) against a website. This mostly affects websites with publicly exposed and particularly large/complex graphql schemas. If your Silverstripe CMS project does not expose a public facing graphql schema, a user account is required to trigger the DDOS attack. If your site is hosted behind a content delivery network (CDN), such as Imperva or CloudFlare, this will likely further mitigate the risk. Upgrade to `silverstripe/graphql` 4.2.3 or 4.1.2 or above to remedy the vulnerability.
