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 unbounded CPU and memory consumption, resulting in a denial of service (DoS) against HTTP services that have baggage propagation enabled.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Important · updated 2026-09-26 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-50274.json)\n\n**github.com/DataDog/dd-trace-go: Datadog dd-trace-go: Denial of Service via malicious baggage headers** — rated Important by Red Hat.
