Vulnerability details

The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to uncontrolled resource consumption in Spring Expression Language (SpEL) expression evaluation when processing user-supplied expressions that use the power operator with a BigDecimal or BigInteger operand and a large exponent value. A remote attacker can submit a specially crafted expression to cause a denial of service.

Exploitation requires that the application accept and evaluate untrusted SpEL expressions and that a BigDecimal or BigInteger value be accessible within the evaluation context.
