Prior to 6.1.0, the decoder reads the four-byte length of a map32 value before validating that the complete five-byte header is available. A truncated map32 header therefore causes a checked out-of-bounds buffer read and throws RangeError instead of IncompleteBufferError, which can unexpectedly terminate a request, stream, or worker in applications that wait for additional bytes after IncompleteBufferError. There is no adjacent-memory disclosure because the buffer implementation checks bounds. This issue is fixed in version 6.1.0.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 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,"severity":null}],"references":["https://github.com/mcollina/msgpack5/security/advisories/GHSA-8f34-f56x-9xph","https://github.com/mcollina/msgpack5/commit/15443a1f2aa682a6aa37f1705ac628de5b866ad1","https://github.com/mcollina/msgpack5/releases/tag/v6.1.0"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-95114","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Oct 8, 2026, 5:14:19 PM","dateUpdated":"Oct 19, 2026, 7:29:15 PM"},"relatedAdvisories":[{"id":"msrc_CVE-2026-107302","title":"msgpack5: Truncated map32 headers throw an unexpected error","vulnerabilityIds":["CVE-2026-107302"]}],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
