What is CVE-2025-32380?

A vulnerability affecting the Apollo Router Core allows for excessive resource consumption when processing deeply nested and reused named fragments. This could lead to denial of service as validation becomes prohibitively expensive. The Apollo Router's integration with the Apollo Compiler has been updated to improve efficiency by ensuring each named fragment is processed only once, successfully mitigating this issue in the specified versions.
