CVE-2026-93450

Estado: Pendiente de análisisAlta (8.7)—

go-openapi/swag jsonutils before 0.27.1 contains a stack overflow vulnerability in ordered JSON parsing and serialization due to unbounded recursion with no depth limit. Remote unauthenticated attackers can submit deeply nested JSON documents to services accepting OpenAPI specifications, causing fatal stack overflow that terminates the process and all in-flight requests.

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.

Vulnerabilidad remota sin autenticación (AV:N/PR:N) en parseo JSON de aplicación expuesta. Ataque genera desbordamiento de pila por recursión ilimitada, causando DoS y pérdida de servicio con interrupción de solicitudes en vuelo.

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.
