By sending an indefinite sequence of bytes with values `0x80` or above, a client can make the server parse these bytes into an ever-growing integer. Since JavaScript numbers are 64-bit floating point values, this number will eventually lose precision and lead to the subsequent payload being parsed incorrectly.\n\n### Patches\n\nThe issue has been patched in version 0.7.5 by rejecting the message if the length header exceeds the configured maximum message length. All users should upgrade to this version.\n\n### Workarounds\n\nNo known workarounds exist.\n\n### Acknowledgements\n\nThis issue was discovered and reported by Pranjali Thakur, DepthFirst Security Research Team.","state":0,"publishedAt":"2026-07-15T22:07:24+00:00","modifiedAt":"2026-09-10T03:51:12.6710934+00:00","affected":[{"ecosystem":"npm","name":"websocket-driver","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"0.7.5"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:H/SA:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"CRITICAL"}],"references":["https://github.com/faye/websocket-driver-node/security/advisories/GHSA-xv26-6w52-cph6","https://github.com/faye/websocket-driver-node","https://github.com/faye/websocket-driver-node/releases/tag/0.7.5"],"sourceUrl":"https://github.com/advisories/GHSA-xv26-6w52-cph6","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-xv26-6w52-cph6","identifiers":["GHSA-xv26-6w52-cph6","CVE-2026-54466"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
