+# composer audit
+
+> Analyze a PHP project's dependencies to detect known security vulnerabilities and list affected packages.
+> See also: `composer`.
+> More information: <https://getcomposer.org/doc/03-cli.md#audit>.
+
+- Check for security vulnerabilities in your current project:
+
+`composer audit`
+
+- Omit dev dependencies in the audit:
+
+`composer audit --no-dev`
+
+- Filter vulnerabilities by output format:
+
+`composer audit --format {{table|plain|json|summary}}`
+
+- Output audit results to a file in JSON format:
+
+`composer audit --format json > audit_report.json`
+
+- Verify whether a specific package in your project is affected by security issues:
+
+`composer audit {{vendor}}/{{package}}`
