Technical details
A resource exhaustion vulnerability exists in dd-trace-js prior to version 5.100.0. The W3C baggage propagation logic in `packages/dd-trace/src/baggage.js` and `packages/dd-trace/src/opentracing/propagation/text_map.js` parses incoming HTTP headers without enforcing the `DD_TRACE_BAGGAGE_MAX_ITEMS` or `DD_TRACE_BAGGAGE_MAX_BYTES` limits during the extraction phase. A remote, unauthenticated attacker can provide a baggage header with an arbitrarily large number of key-value pairs or extremely large values. This causes unbounded CPU and memory consumption, leading to a Denial of Service (DoS). The issue is resolved in version 5.100.0 by mirroring the injection-side caps during extraction.
