Annotation: This article presents a method for detecting and eliminating floating vulnerabilities in mobile applications at the final stage of development. The nature of such vulnerabilities is analyzed and existing methods of their detection and neutralization are considered. The developed method is based on analyzing the state of the application at different points in time and comparing it with the reference state. It includes fixing the initial state, discrete analysis of its changes, detection and identification of vulnerabilities, their elimination. The main area of application of the method is to ensure the security of mobile applications at late stages of development and in the process of final testing. The conclusions of the article emphasize the importance of early detection of floating vulnerabilities to ensure a high level of information security of the final (final) software product

Keywords: floating vulnerabilities, mobile applications, program testing, state estimation, information security
