{"cve":"CVE-2025-32032","nvd":{"published":"2025-04-07T21:15:43.363","modified":"2026-06-17T09:11:21.217","status":"Deferred","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 allowed queries with deeply nested and reused named fragments to be prohibitively expensive to query plan, specifically due to internal optimizations being frequently bypassed. The query planner includes an optimization that significantly speeds up planning for applicable GraphQL selections. However, queries with deeply nested and reused named fragments can generate many selections where this optimization does not apply, leading to significantly longer planning times. Because the query planner does not enforce a timeout, a small number of such queries can exhaust router's thread pool, rendering it inoperable. This could lead to excessive resource consumption and denial of service. This has been remediated in apollo-router versions 1.61.2 and 2.1.1.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-770"],"references":["https://github.com/apollographql/router/commit/ab6675a63174715ea6ff50881fc957831d4e9564","https://github.com/apollographql/router/commit/bba032e183b861348a466d3123c7137a1ae18952","https://github.com/apollographql/router/security/advisories/GHSA-94hh-jmq8-2fgp"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:00:57.946988208+00:00"},"epss":{"cve":"CVE-2025-32032","score":0.00596,"percentile":0.48523,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-94hh-jmq8-2fgp","url":"https://osv.dev/vulnerability/GHSA-94hh-jmq8-2fgp","summary":"Apollo Router Query Planner Vulnerable to Excessive Resource Consumption via Optimization Bypass","modified":"2025-04-08T17:50:00Z","packages":[{"ecosystem":"crates.io","name":"apollo-router","purl":"pkg:cargo/apollo-router","ranges":["<1.61.2"],"fixed":["1.61.2"]},{"ecosystem":"crates.io","name":"apollo-router","purl":"pkg:cargo/apollo-router","ranges":[">=2.0.0-alpha.0 <2.1.1"],"fixed":["2.1.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
