CVE-2026-34043
Serialize JavaScript to a superset of JSON that includes regular expressions and functions.
Published Mar 31, 2026 · updated Jun 17, 2026 · yahoo serialize
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.
