A vulnerability is a weakness which allows an attacker to reduce a system's information assurance. Vulnerability is the intersection of three elements: a system susceptibility or flaw, attacker access to the flaw, and attacker capability to exploit the flaw. To exploit a vulnerability, an attacker must have at least one applicable tool or technique that can connect to a system weakness, known as the attack surface. Vulnerability management is the cyclical practice of identifying, classifying, remediating, and mitigating vulnerabilities. Other vulnerabilities include security risks, security defects and constructs in programming languages that are difficult to use properly.

Some browsers require the use of add-ons or extensions to safely render the information they receive; others have systems built into them to perform the same functions.
