An unauthenticated user can send overly complex queries that bypass the system&#8217;s query complexity limits. This leads to resource exhaustion as the system attempts to process these queries, causing service disruption and potentially allowing for further attacks on the system.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-1230828209\" class=\"ameeb-content ameeb-entity-placement\"><div class=\"poptin-embedded\" data-id=\"f6b387694f681\"><\/div>\r\n\r\n\r\n\r\n\r\n\r\n<\/div>\n<p>Consider the following example of a malicious GraphQL query that could exploit this vulnerability:<\/p>\n<pre><code class=\"\" data-line=\"\">POST \/api\/graphql HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{\n&quot;query&quot;: &quot;{ user(id: &#039;1&#039;) { posts { title, content, comments { text } } } }&quot;\n}<\/code><\/pre>\n<p>In this example, the query is requesting a large amount of data (all posts, their titles, contents, and all associated comments) for a single user.
