Hi,

The following vulnerability was published for node-serialize-javascript.

CVE-2026-34043[0]:
| 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.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
