Uncontrolled Resource Consumption is a cybersecurity vulnerability where software fails to properly limit the use of system resources such as CPU, memory, disk space, or network bandwidth. Attackers can exploit this flaw by sending specially crafted requests or inputs that force an application or system to consume excessive resources. This can lead to degraded performance, denial of service (DoS), or even system crashes, affecting availability and reliability. The root cause is often a lack of input validation or resource management, allowing users or attackers to trigger resource-intensive operations. Proper coding practices, resource quotas, and input validation are essential to prevent this vulnerability.
