Information Disclosure is a cybersecurity vulnerability where sensitive, confidential, or private data is unintentionally exposed to unauthorized individuals. This can happen through software bugs, misconfigurations, or weak security controls, allowing attackers to access data such as personal information, business secrets, or system details. Information disclosure can lead to privacy breaches, identity theft, or further exploitation of systems. Preventing this vulnerability involves regularly updating software, properly configuring systems, and applying strict access controls to ensure only authorized users can view sensitive information.
