CVE-2026-50274Network attack vector

Remote service interruption via unbounded baggage extraction

Published Jul 17, 2026 · Updated Jul 17, 2026

Resource exhaustion in Datadog dd-trace-go before 2.8.1 allows remote attackers to interrupt HTTP services through baggage headers. The propagatorBaggage.extractTextMap method allocates entries while parsing untrusted W3C baggage without enforcing item or byte limits. The attack requires baggage extraction, enabled by default in most affected tracers, and can exhaust service CPU and memory.
