Values produced by ${random.value} are not suitable for use as secrets. ${random.uuid} is not affected. ${random.int} an

Values produced by ${random.value} are not suitable for use as secrets. ${random.uuid} is not affected. ${random.int} and ${random.long} should never be used for secrets as they are numeric values with a predictable range. Affected: Spring Boot 4.0.0-4.0.5 (fix 4.0.6), 3.5.0-3.5.13 (fix 3.5.14), 3.4.0-3.4.15 (fix 3.4.16), 3.3.0-3.3.18 (fix 3.3.19), 2.7.0-2.7.32 (fix 2.7.33)

random value property source / weak PRNG for secrets. Versions that are no longer supported are also affected per vendor advisory.
