While the number of content-encoding layers is capped, the total decompressed output size is unbounded and there is no configuration option to limit it. A malicious or faulty upstream can therefore return a small compressed payload, a compression bomb, that expands to hundreds of megabytes or more in client memory, an asymmetric resource consumption that can exhaust memory and crash the process. This affects undici versions from 7.15.0 up to 7.29.1 and from 8.0.0 up to 8.10.2. Users should upgrade to undici 7.29.1 or 8.10.2.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","score":5.9,"severity":null}],"references":["https://github.com/nodejs/undici/security/advisories/GHSA-3xpg-4rpp-hhhm","https://cna.openjsf.org/security-advisories.html"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-71634","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Sep 4, 2026, 5:04:28 PM","dateUpdated":"Sep 4, 2026, 6:33:28 PM"},"relatedAdvisories":[{"id":"RHSA-2026:66008","title":"Red Hat Security Advisory: Red Hat Hardened Images RPMs bug fix and enhancement update","vulnerabilityIds":["CVE-2026-14199","CVE-2026-18149","CVE-2026-18540","CVE-2026-19197","CVE-2026-19534","CVE-2026-28378","CVE-2026-84890","CVE-2026-84933","CVE-2026-84947","CVE-2026-84961","CVE-2026-85008","CVE-2026-85014"]},{"id":"openSUSE-SU-2026:22111-1","title":"Security update for pi-coding-agent","vulnerabilityIds":["CVE-2026-102276","CVE-2026-102277","CVE-2026-102278","CVE-2026-84890","CVE-2026-84933","CVE-2026-84947","CVE-2026-84961","CVE-2026-85008","CVE-2026-85014","CVE-2026-85024","CVE-2026-85152"]},{"id":"RHSA-2026:54438","title":"Red Hat Security Advisory: Red Hat Hardened Images RPMs bug fix and enhancement update","vulnerabilityIds":["CVE-2026-18149","CVE-2026-48932","CVE-2026-84890","CVE-2026-84933","CVE-2026-84947","CVE-2026-84961","CVE-2026-85008","CVE-2026-85014","CVE-2026-85152"]},{"id":"RHSA-2026:54389","title":"Red Hat Security Advisory: Red Hat Hardened Images RPMs Security Update","vulnerabilityIds":["CVE-2026-14257","CVE-2026-18149","CVE-2026-48932","CVE-2026-69152","CVE-2026-84890","CVE-2026-84933","CVE-2026-84947","CVE-2026-85008","CVE-2026-85014","CVE-2026-85152"]}],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
