CVE-2026-50276Network attack vectorHinoki check available

Unauthenticated denial of service via unbounded baggage extraction

Published Sep 14, 2026 · Updated Sep 14, 2026

Resource exhaustion in Datadog Ruby Trace Client before 2.32.0 allows remote attackers to interrupt HTTP services via baggage headers. The W3C baggage extraction path enforces neither item-count nor byte-size limits and allocates a hash-map entry for each attacker-controlled pair. Baggage extraction must be enabled, as it is by default in most affected tracers; repeated oversized headers consume unbounded CPU and memory.
