CVE-2025-32032

Estado: AplazadaAlta (7.5)—

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.

Leer descripción completaMostrar menos

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

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Vector CVSS AV:N/AC:L/PR:N sin UI permite explotación remota sin autenticación (T1190). CWE-770 y descripción explícita de agotamiento de recursos del thread pool generan DoS (T1499.004).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.

      "value": "Apollo Router Core es un enrutador de grafos configurable y de alto rendimiento, escrito en Rust para ejecutar un supergrafo federado que utiliza Apollo Federation 2. Una vulnerabilidad en Apollo Router hacía que la planificación de consultas con fragmentos con nombre profundamente anidados y reutilizados fuera prohibitivamente costosa, especialmente debido a que las optimizaciones internas se omitían con frecuencia. El planificador de consultas incluye una optimización que acelera significativamente la planificación de las selecciones GraphQL aplicables. Sin embargo, las consultas con fragmentos con nombre profundamente anidados y reutilizados pueden generar muchas selecciones donde esta optimización no aplica, lo que resulta en tiempos de planificación significativamente más largos. Dado que el planificador de consultas no impone un tiempo de espera, un pequeño número de estas consultas puede agotar el grupo de subprocesos del enrutador, dejándolo inoperativo. Esto podría provocar un consumo excesivo de recursos y denegación de servicio. Esto se ha solucionado en las versiones 1.61.2 y 2.1.1 de apollo-router."
