{"id":"DEBIAN-CVE-2026-34043","details":"Serialize JavaScript to a superset of JSON that includes regular expressions and functions. Prior to version 7.0.5, there is a Denial of Service (DoS) vulnerability caused by CPU exhaustion. When serializing a specially crafted \"array-like\" object (an object that inherits from Array.prototype but has a very large length property), the process enters an intensive loop that consumes 100% CPU and hangs indefinitely. This issue has been patched in version 7.0.5.","modified":"2026-09-01T16:06:40.261446745Z","published":"2026-03-31T03:15:58.400Z","upstream":["CVE-2026-34043"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-34043"}],"affected":[{"package":{"name":"node-serialize-javascript","ecosystem":"Debian:12","purl":"pkg:deb/debian/node-serialize-javascript?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.0.0-2","6.0.0-2+deb12u1","6.0.1-1","6.0.2-1","7.0.4+~5.0.4-1","7.0.5+~5.0.4-1","7.0.7+~5.0.4-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-34043.json"}},{"package":{"name":"node-serialize-javascript","ecosystem":"Debian:13","purl":"pkg:deb/debian/node-serialize-javascript?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.0.2-1","7.0.4+~5.0.4-1","7.0.5+~5.0.4-1","7.0.7+~5.0.4-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-34043.json"}},{"package":{"name":"node-serialize-javascript","ecosystem":"Debian:14","purl":"pkg:deb/debian/node-serialize-javascript?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.0.5+~5.0.4-1"}]}],"versions":["6.0.2-1","7.0.4+~5.0.4-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-34043.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
