CVE-2026-50276

dd-trace-rb (Datadog's Ruby tracing library) is affected by a remote Denial of Service vulnerability (CVSS 7.5, HIGH) in its W3C baggage header extraction path. Prior to version 2.32.0 , the limits DD_TRACE_BAGGAGE_MAX_ITEMS (default 64) and DD_TRACE_BAGGAGE_MAX_BYTES (default 8192) were enforced...

CVE-2026-50270

dd-trace-java (Datadog APM client for Java) versions prior to 1.62.0 are vulnerable to a remote Denial of Service due to improper parsing of W3C baggage headers. The extraction path in BaggagePropagator.java allocates a hash-map entry for each comma-separated key-value pair without enforcing DD_T...
