+## Troubleshooting
+
+### Composer Security Advisories
+When working with **Shopware 6.5.x**, you may encounter a build failure during `composer update` or `composer install`. This is caused by the **Composer Audit** feature (introduced in Composer 2.7+), which automatically blocks the installation of packages with known security vulnerabilities.
+
+The error message typically looks like this:
+`...these were not loaded, because they are affected by security advisories (PKSA-...)`
+
+### Recommended Solution: Upgrade
+The most effective and secure way to resolve this is to **upgrade to the latest version of our plugin** and, if possible, move to **Shopware 6.7+**.
 
+The latest versions provide:
+* **Security Patches:** Protection against the vulnerabilities flagged by Composer.
+* **Stability:** Improved compatibility with modern PHP versions and server environments.
+* **Performance:** Optimized code execution for faster storefront response times.
