CVE-2026-50270 is a denial-of-service vulnerability in Datadog's dd-trace-java library affecting parsing of W3C baggage propagation headers during trace context extraction. Improper handling of oversized or highly fragmented baggage header values can cause unbounded CPU and memory consumption while the tracer processes inbound HTTP requests. The issue is reachable remotely through crafted HTTP requests sent to services instrumented with the Java tracer and exposed over the network.
