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.\n\n**Who is impacted?**\n\nApplications that use `serialize-javascript` to serialize untrusted or user-controlled objects are at risk. While direct exploitation is difficult, it becomes a high-priority threat if the application is also vulnerable to **Prototype Pollution** or handles untrusted data via **YAML Deserialization**, as these could be used to inject the malicious object.\n\n### Patches\n\n**Has the problem been patched?**\n\nYes, the issue has been patched by replacing `instanceof Array` checks with `Array.isArray()` and using `Object.keys()` for sparse array detection.\n\n**What versions should users upgrade to?**\n\nUsers should upgrade to **`v7.0.5`** or later.\n\n### Workarounds\n\n**Is there a way for users to fix or remediate the vulnerability without upgrading?**\n\nThere is no direct code-level workaround within the library itself. However, users can mitigate the risk by:\n\n* Validating and sanitizing all input before passing it to the `serialize()` function.\n* Ensuring the environment is protected against Prototype Pollution.\n* Upgrading to **`v7.0.5`** as soon as possible.\n\n### Acknowledgements\n\nSerialize JavaScript thanks **Tomer Aberbach** (@TomerAberbach) for discovering and privately disclosing this
