Technical details
Adobe Commerce versions up to 2.4.9-beta1 are vulnerable to uncontrolled resource consumption (CWE-400). The vulnerability exists in the application's handling of incoming requests, where an attacker can trigger excessive resource allocation. This is a network-based attack that requires no authentication (PR:N) and no user interaction (UI:N). Successful exploitation allows a remote attacker to exhaust CPU or memory resources, resulting in a complete denial-of-service for the application. Users are advised to update to the latest patched versions provided by Adobe.
