Dependency audits check locked package versions for known vulnerability advisories.
What It Does
Dependency audits check locked package versions for known vulnerability advisories. The following examples distinguish a normal use case, a boundary case and a practical application.
Requirements and Compatibility
Composer installed and a version-controlled composer.json; lockfile behavior differs between applications and libraries.
The code focuses on the core concept. Production implementation may also need routes, validation, persistence, authorization or deployment tooling.
Example 1: Basic Behavior
Check Composer metadata and security advisories against your lock file.
composer validate --strict
composer audit --lockedThis is a command-line example; use it in its appropriate file or shell, not in the PHP source editor.
Example 2: Another Case
Inspect direct dependency updates and installed platform packages before upgrading.
composer outdated --direct
composer show --platformThis is a command-line example; use it in its appropriate file or shell, not in the PHP source editor.
Practical Example: Putting It to Use
Update one reviewed dependency with transitive requirements, then test and commit composer.lock.
composer update vendor/package --with-dependencies
composer check-platform-reqsThis is a command-line example; use it in its appropriate file or shell, not in the PHP source editor.
Important Behavior and Edge Cases
A clean audit cannot prove a dependency is safe from unknown vulnerabilities or malicious releases.

Common Beginner Mistakes
| Mistake | Correct approach |
|---|---|
| Ignoring the important boundary for Auditing Dependencies for Vulnerabilities | A clean audit cannot prove a dependency is safe from unknown vulnerabilities or malicious releases. |
| Assuming a related mechanism has the same behavior | Combine composer audit with supported versions and reviewed upgrades. |

- Combine composer audit with supported versions and reviewed upgrades.
Before adapting these examples, verify the return values, test the failure paths and confirm that your application meets its security and environment requirements.
