Denial of Service Vulnerability in Apollo Router Core by Apollo GraphQL
CVE-2025-32032
7.5HIGH
What is CVE-2025-32032?
Apollo Router Core, a high-performance graph router built in Rust, contains a vulnerability that allows queries with deeply nested and reused named fragments to create excessive load during query planning. This flaw bypasses internal optimizations of the query planner, causing significant delays in processing and leading to potential denial of service. The absence of a timeout mechanism allows these costly queries to consume available threads, ultimately rendering the router inoperative. Users are encouraged to upgrade to Apollo Router versions 1.61.2 or 2.1.1 to mitigate this issue.

router < 1.61.2 < 1.61.2
