Malicious data is used to reconstitute objects in an application, potentially allowing attackers to execute arbitrary code or manipulate system behavior. This flaw often arises in applications that rely on serialized data formats (like JSON or XML) without proper input validation. Cybercriminals exploit this weakness to gain unauthorized access, escalate privileges, or disrupt services. To mitigate the risk, developers must implement input validation, use safe serialization frameworks, and apply strict access controls. Regular code audits and security testing are essential. Addressing deserialization vulnerabilities is crucial for maintaining the integrity and security of software applications.
