Prior to 1.6.8, fromJSON and fromCrossJSON do not validate a sequence node's done index. A crafted done index can create an iterator that never finishes when application code consumes it to completion. An unauthenticated request to a service that deserializes untrusted input can therefore block the event loop, exhaust process memory, or make the service unavailable. This issue is fixed in version 1.6.8."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"lxsmnsyc","product":"seroval","versions":[{"version":"< 1.6.8","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":3.6}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Primary","description":[{"lang":"en","value":"CWE-835"},{"lang":"en","value":"CWE-1284"}]}],"references":[{"url":"https://github.com/lxsmnsyc/seroval/commit/e176f9267e59ddd6c9de89cc9fe85c5b37a5b728","source":"security-advisories@github.com"},{"url":"https://github.com/lxsmnsyc/seroval/releases/tag/seroval@1.6.8","source":"security-advisories@github.com"},{"url":"https://github.com/lxsmnsyc/seroval/security/advisories/GHSA-97r2-qh9m-474h","source":"security-advisories@github.com"}]}
