CVE-2026-116581
highSeroval facilitates JavaScript value stringification, including complex structures beyond JSON.stringify capabilities.
Seroval facilitates JavaScript value stringification, including complex structures beyond JSON.stringify capabilities. 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.
