Technical details
A Server-Side Request Forgery (SSRF) vulnerability exists in Spatie Laravel Media Library before version 11.23.0. The vulnerability is located in the addMediaFromUrl() method within InteractsWithMedia.php, which fails to sufficiently validate user-supplied URLs. A remote attacker with low privileges can provide a malicious URL, causing the server to initiate arbitrary outbound HTTP requests. This can be used to probe internal network services, bypass firewalls, or access metadata services in cloud environments. The issue was addressed in version 11.23.0 by hardening filename validation and documenting SSRF boundaries.
