  "details" : [ "A flaw was found in Spring Boot. The `${random.value}` property source utilizes a weak pseudo-random number generator (PRNG), meaning the values it produces are not sufficiently random for use as cryptographic secrets. An attacker could potentially predict these values, which may lead to information disclosure or a security bypass if they are used in sensitive applications." ],
