What Is Exploit?
A piece of code, technique, or sequence of actions that takes advantage of a vulnerability to produce unintended behavior. Exploits turn theoretical vulnerabilities into actual security breaches.
In Laravel Applications
An exploit against a Laravel application might use a known CVE in a Composer dependency, a SQL injection in a raw query, or a forged session cookie created using a leaked APP_KEY.
Example
If APP_KEY is leaked through an exposed .env file, an attacker can exploit this by forging encrypted session cookies to impersonate any user, including administrators.

Vulnerability
A weakness in a system that can be exploited by an attacker to perform unauthorized actions. Vulnerabilities can exist in code, configuration, infrastructure, or processes. They range in severity from informational to critical.
CVE (Common Vulnerabilities and Exposures)
A standardized identifier for publicly known security vulnerabilities. Each CVE entry includes a unique ID (e.g., CVE-2024-1234), a description, and severity rating. The CVE system is maintained by MITRE and used globally to track and reference vulnerabilities.
Zero-Day Vulnerability
A vulnerability that is unknown to the software vendor and has no available patch. The term "zero-day" refers to the fact that developers have had zero days to fix the issue. Zero-day exploits are particularly dangerous because no defense exists until the vendor releases a patch.
