| Doc Text: |
A flaw was found in Active Support, a toolkit of support libraries for Ruby on Rails. A remote attacker can exploit this vulnerability by providing specially crafted strings containing scientific notation (e.g., "1e10000") to number helpers. This input causes the `BigDecimal` component to expand into extremely large decimal representations, consuming excessive memory and CPU resources. This can lead to a Denial of Service (DoS) vulnerability, making the affected system unavailable.
