VCID-vn8z-q24d-57bu Aliases: CVE-2026-34043 GHSA-qj8w-gfj5-8c6v	Serialize JavaScript has CPU Exhaustion Denial of Service via crafted array-like objects ### Impact What kind of vulnerability is it? It 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. Who is impacted? Applications 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. ### Patches Has the problem been patched? Yes, the issue has been patched by replacing `instanceof Array` checks with `Array.isArray()` and using `Object.keys()` for sparse array detection. What versions should users upgrade to? Users should upgrade to `v7.0.5` or later. ### Workarounds Is there a way for users to fix or remediate the vulnerability without upgrading? There is no direct code-level workaround within the library itself. However, users can mitigate the risk by: * Validating and sanitizing all input before passing it to the `serialize()` function. * Ensuring the environment is protected against Prototype Pollution. * Upgrading to `v7.0.5` as soon as possible. ### Acknowledgements Serialize JavaScript thanks Tomer Aberbach (@TomerAberbach) for discovering and privately disclosing this issue.	7.0.5+~5.0.4-1 Affected by 0 other vulnerabilities.
