Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Improper handling of W3C baggage headers in github.com/DataDog/dd-trace-go/v2 before 2.8.1, and in github.com/DataDog/dd-trace-go up to 1.24.1 (no fixed version listed), lets extraction parse baggage without item-count or size limits. A remote, unauthenticated attacker can send a request with a very large baggage header, causing unbounded CPU and memory use and a denial of service. Upgrade github.com/DataDog/dd-trace-go/v2 to 2.8.1 or later. If upgrading is not possible, remove baggage from the propagation style settings or cap HTTP request header size at an upstream proxy.
