A vulnerability is a type of security risk that can exist in a computer or a computer system. It could be a design flaw or a software error that allows an attacker to exploit the system in a way that wasn't intended.
By exploiting a vulnerability, an attacker might gain unauthorized access to the system or to confidential information stored on it. It's essential to identify and address vulnerabilities to prevent the system from being susceptible to attacks.
Known technical vulnerabilities or CVEs (Common Vulnerabilities and Exposures) are publicly known vulnerabilities that the tool identifies by matching against various databases.
