Title
dd-trace-go: Improper parsing of W3C baggage headers may lead to DoS
Summary
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.
