Detailsinfo

A vulnerability was found in DataDog dd-trace-go up to 2.8.0. It has been declared as problematic. This vulnerability affects an unknown code of the component Baggage Propagation. The manipulation with an unknown input leads to a denial of service vulnerability. The CWE definition for the vulnerability is CWE-404.

Datadog dd-trace-go is a Go client library for Datadog application performance monitoring, profiling, and security monitoring. Prior to 2.8.1, Datadog tracing libraries that implement W3C baggage propagation parse incoming baggage HTTP headers without enforcing DD_TRACE_BAGGAGE_MAX_ITEMS or DD_TRACE_BAGGAGE_MAX_BYTES limits on the extract path. 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 HTTP services with baggage propagation enabled. This issue is fixed in version 2.8.1.

The advisory is available at github.com. This vulnerability was named CVE-2026-50274 since 06/04/2026. The exploitation appears to be easy. The attack can be initiated remotely.
