    A security vulnerability, identified as CVE-2023-50164, has been discovered in Apache Struts, a popular, open-source framework for building Java web applications.


    The vulnerability affects the file upload functionality of versions prior to Apache Struts 2.5.33 and Struts The problem stems from how the framework handles the HTTP parameters related to file uploading.
