WPGraphQL is a popular WordPress plugin that provides a GraphQL API for interacting with site data. A security flaw allows unauthenticated attackers to perform SQL injection, which could lead to the theft of sensitive information from the website's database. This vulnerability poses a significant risk as it can be exploited remotely without any login credentials, potentially impacting site operations and data privacy.
