What Is 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.
In Laravel Applications
Laravel and its dependencies receive CVE assignments when vulnerabilities are discovered. Run `composer audit` to check your project against the CVE database. Packages like symfony/http-foundation and guzzlehttp/guzzle frequently have CVEs that affect Laravel applications.
Example
CVE-2021-43617 affected Laravel's password reset functionality. Teams using `composer audit` could detect and patch this before exploitation.
