CWE-402 (将私有的资源传输到一个新的空间(资源泄露)) — Vulnerability Class 22

CWE-402 represents a critical security weakness where software inadvertently exposes internal resources to untrusted external entities, violating intended access boundaries. This flaw typically arises when applications fail to properly validate or sanitize data during transmission, allowing attackers to intercept sensitive information such as session tokens, configuration details, or private user data. Exploitation often involves network sniffing or man-in-the-middle attacks, enabling adversaries to gain unauthorized access or escalate privileges by leveraging these leaked resources. To mitigate this risk, developers must implement robust access controls and encryption protocols, ensuring that data remains confidential during transit. Strict input validation and adherence to the principle of least privilege further prevent accidental exposure, safeguarding system integrity against unauthorized disclosure and maintaining trust within the application’s operational sphere.
