Access Control Bypass is a cybersecurity vulnerability where an attacker exploits weaknesses or flaws in a system’s access control mechanisms to gain unauthorized access to restricted resources, data, or functionalities. This means that individuals can reach sensitive information or perform actions they are not permitted to, often by manipulating URLs, exploiting software bugs, or leveraging misconfigurations. Such bypasses can lead to data breaches, loss of privacy, or unauthorized system changes. Effective access control is essential to prevent these risks and protect sensitive assets from malicious actors.
