CVE-2025-32380 Apollo Router Query Validation Vulnerable to Excessive Resource Consumption via Named Fragment Processing

What is CVE-2025-32380?

CVE-2025-32380 is a high-severity denial of service vulnerability in apollographql router, published on 9 Apr 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official description

The Apollo Router Core is a configurable, high-performance graph router written in Rust to run a federated supergraph that uses Apollo Federation 2. A vulnerability in Apollo Router's usage of Apollo Compiler allowed queries with deeply nested and reused named fragments to be prohibitively expensive to validate. This could lead to excessive resource consumption and denial of service. Apollo Router's usage of Apollo Compiler has been updated so that validation logic processes each named fragment only once, preventing redundant traversal. This has been remediated in apollo-router versions 1.61.2 and 2.1.1.

Weakness: CWE-770
