Prior to 5.100.0, W3C baggage propagation in packages/dd-trace/src/baggage.js and packages/dd-trace/src/opentracing/propagation/text_map.js parsed incoming baggage HTTP headers without enforcing DD_TRACE_BAGGAGE_MAX_ITEMS or DD_TRACE_BAGGAGE_MAX_BYTES on extraction. A remote, unauthenticated attacker can send a request whose baggage header contains an arbitrarily large number of comma-separated key-value pairs, or a single very large value, causing unbounded CPU and memory consumption and enabling a remote denial of service against any HTTP service with baggage propagation enabled. This issue is fixed in version 5.100.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-770"],"references":["https://github.com/DataDog/dd-trace-js/commit/a7d4c0da05f67cde05a99272b725a317c461d0e6","https://github.com/DataDog/dd-trace-js/pull/8255","https://github.com/DataDog/dd-trace-js/releases/tag/v5.100.0","https://github.com/DataDog/dd-trace-js/security/advisories/GHSA-wxqq-gcq8-c443"],"products":[],"source":"nvd","synced_at":"2026-10-25T17:50:08.599881581+00:00"},"epss":{"cve":"CVE-2026-50272","score":0.00793,"percentile":0.56073,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-wxqq-gcq8-c443","url":"https://osv.dev/vulnerability/GHSA-wxqq-gcq8-c443","summary":"dd-trace-js: Improper parsing of W3C baggage headers may lead to DoS","modified":"2026-09-10T03:51:12.462066874Z","packages":[{"ecosystem":"npm","name":"dd-trace","purl":"pkg:npm/dd-trace","ranges":["<5.100.0"],"fixed":["5.100.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
