CVE-2026-50272

Full vulnerability record from the local CVENow database.

Description

dd-trace is the Datadog APM client for Node.js. Prior to 5.100.0, W3C baggage propagation in packages/dd-trace/src/baggage.js and packages/dd-trace/src/opentracing/propagation/text_map.js parsed incoming baggage HTTP headers without enforcing DD_TRACE_BAGGAGE_MAX_ITEMS or DD_TRACE_BAGGAGE_MAX_BYTES on extraction. A remote, unauthenticated attacker can send a request whose baggage header contains an arbitrarily large number of comma-separated key-value pairs, or a single very large value, causing unbounded CPU and memory consumption and enabling a remote denial of service against any HTTP service with baggage propagation enabled. This issue is fixed in version 5.100.0.

Antes de 5.100.0, la propagación de equipaje W3C en packages/dd-trace/src/baggage.js y packages/dd-trace/src/opentracing/propagation/text_map.js analizaba los encabezados HTTP de equipaje entrantes sin aplicar DD_TRACE_BAGGAGE_MAX_ITEMS o DD_TRACE_BAGGAGE_MAX_BYTES en la extracción. Un atacante remoto y no autenticado puede enviar una solicitud cuyo encabezado de equipaje contenga un número arbitrariamente grande de pares clave-valor separados por comas, o un único valor muy grande, causando un consumo ilimitado de CPU y memoria y permitiendo una denegación de servicio remota contra cualquier servicio HTTP con la propagación de equipaje habilitada. Este problema está solucionado en la versión 5.100.0."
