| Doc Text: |
A flaw was found in serialize-javascript. An attacker can exploit this vulnerability by providing a specially crafted "array-like" object with an excessively large length property during the serialization process. This action causes the application to enter an intensive loop, leading to 100% CPU consumption and an indefinite hang. The primary consequence is a Denial of Service (DoS), making the affected system unresponsive.
