CVE-2026-50274

A flaw was found in Datadog dd-trace-go, a Go client library. A remote, unauthenticated attacker can exploit this vulnerability by sending a request with a specially crafted baggage header containing an arbitrarily large number of key-value pairs or a very large single value. This can lead to...

opentelemetry-java: opentelemetry-api: opentelemetry-extension-trace-propagators: OpenTelemetry Java: Denial of Service due to unbounded memory allocation when parsing oversized baggage

A flaw was found in OpenTelemetry Java, specifically within the baggage propagation implementation of opentelemetry-api and opentelemetry-extension-trace-propagators. A remote attacker can exploit this vulnerability by sending oversized baggage, which leads to unbounded memory allocation and high...

CVE-2026-50272 dd-trace: Improper parsing of W3C baggage headers may lead to DoS

dd-trace is the Datadog APM client for Node.js. Prior to 5.100.0, W3C baggage propagation in packages/dd-trace/src/baggage.js and packages/dd-trace/src/opentracing/propagation/textmap.js parsed incoming baggage HTTP headers without enforcing DDTRACEBAGGAGEMAXITEMS or DDTRACEBAGGAGEMAXBYTES on...

CVE-2026-48504

OpenTelemetry Rust (CVE-2026-48504) concerns BaggagePropagator::extract_with_context in opentelemetry_sdk. In 0.32.0 and earlier, it did not enforce W3C Baggage size limits before parsing an inbound baggage header, allowing an attacker-controlled header to trigger unnecessary CPU work and short-l...

CVE-2026-48504 OpenTelemetry Rust: Unbounded memory allocation in W3C Baggage propagation

OpenTelemetry Rust is the Rust OpenTelemetry implementation. In 0.32.0 and earlier, BaggagePropagator::extractwithcontext in opentelemetrysdk did not enforce W3C Baggage size limits before parsing an inbound baggage header, so a large attacker-controlled header could cause unnecessary CPU work an...

GHSA-MW54-J2V2-42HR dd-trace-py: Improper parsing of W3C baggage headers may lead to DoS

Impact Datadog tracing libraries that implement W3C baggage propagation parse incoming baggage HTTP headers without enforcing item-count or byte-size limits on the extract path. The DDTRACEBAGGAGEMAXITEMS default 64 and DDTRACEBAGGAGEMAXBYTES default 8192 limits were applied only to baggage...
