## Technical details

Adobe Commerce versions up to 2.4.9-beta1 are vulnerable to uncontrolled resource consumption (CWE-400). The vulnerability allows a remote, unauthenticated attacker to send requests that exhaust server-side resources such as CPU, memory, or disk space. This results in an application-level denial-of-service (DoS), making the platform unavailable to users. The attack vector is network-based with low complexity and requires no special privileges or user interaction. Administrators should update to the latest patched versions provided by Adobe to mitigate this risk.
