**Name of the Vulnerable Software and Affected Versions** fast-xml-parser versions prior to 5.3.8 **Description** fast-xml-parser is a tool for XML validation, parsing XML to JavaScript objects, and building XML from JavaScript objects without relying on C/C++ libraries or callbacks. Prior to version 5.3.8, the application is susceptible to a stack overflow when utilizing the XML builder with the `preserveOrder` option set to `true`. This can lead to application crashes. As a temporary measure, using the XML builder with `preserveOrder` set to `false` or validating input data before passing it to the builder can mitigate the issue. **Recommendations** Update to version 5.3.8 or later. As a temporary workaround, use the XML builder with `preserveOrder:false`. Validate input data before passing it to the builder.
