CVE-2026-50270Network attack vectorHinoki check available

Service interruption via unbounded baggage extraction

Published Sep 14, 2026 · Updated Sep 14, 2026

Resource exhaustion in Datadog dd-trace-java before 1.62.0 allows remote attackers to interrupt HTTP services via baggage headers. The W3C baggage extraction path parses attacker-controlled header values into hash-map entries without enforcing the configured item-count or byte-size limits. Exposure requires an instrumented HTTP service with baggage extraction enabled; repeated oversized headers consume unbounded CPU and memory until the service becomes unavailable.
