CVE-2021-43801

Name of the Vulnerable Software and Affected Versions: Mercurius versions 8.10.0 through 8.11.1

Description: The issue affects Mercurius, a GraphQL adapter for Fastify, where users can be subjected to a denial of service attack by sending a malformed JSON to the /graphql API endpoint, unless they are using a custom error handler.

Recommendations: For versions 8.10.0 through 8.11.1, update to version 8.11.2 to resolve the issue. As a temporary workaround for versions 8.10.0 through 8.11.1, consider using a custom error handler to mitigate the risk of exploitation.
