By sending a 256mb websocket message to a uws server instance with permessage-deflate enabled, there is a possibility used compression will shrink said 256mb down to less than 16mb of websocket payload which passes the length check of 16mb payload. This data will then inflate up to 256mb and crash the node process by exceeding V8's maximum string size. This affects uws >=0.10.0 <=0.10.8.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","score":5.9},"cwes":["CWE-20","CWE-400"],"references":["https://github.com/uWebSockets/uWebSockets/commit/37deefd01f0875e133ea967122e3a5e421b8fcd9","https://nodesecurity.io/advisories/149","https://github.com/uWebSockets/uWebSockets/commit/37deefd01f0875e133ea967122e3a5e421b8fcd9","https://nodesecurity.io/advisories/149"],"products":["uws_project:uws"],"source":"nvd","synced_at":"2026-10-19T20:50:40.212176939+00:00"},"epss":{"cve":"CVE-2016-10544","score":0.01319,"percentile":0.70838,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-hf5h-hh56-3vrg","url":"https://osv.dev/vulnerability/GHSA-hf5h-hh56-3vrg","summary":"Denial of Service in uws","modified":"2023-11-08T03:58:11.701417Z","packages":[{"ecosystem":"npm","name":"uws","purl":"pkg:npm/uws","ranges":[">=0.10.0 <0.10.9"],"fixed":["0.10.9"]}]}],"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).
