CVE-2026-50273 (opens in a new tab)How to fix?
Upgrade Datadog.Trace.OpenTracing to version 3.43.0 or higher.
Overview
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling through improper parsing of W3C baggage headers in the extraction process. An attacker can exhaust system resources by sending HTTP requests with a large number of comma-separated key-value pairs or a single excessively large value in the baggage header, resulting in unbounded CPU and memory consumption. This is only exploitable if baggage propagation style is enabled, which is the default in most affected configurations.
Workaround
This vulnerability can be mitigated by disabling baggage extraction via configuration or by capping the maximum HTTP request header size at an upstream proxy or web server.
