This flaw allows attackers to execute arbitrary code or cause a denial of service by crafting large BigDecimal values within a 64-bit process. With a CVSS score of 6.8 (medium severity), it is remotely exploitable with medium attack complexity, potentially leading to partial confidentiality, integrity, and availability compromise.
