The new Random(seed) constructor is called with a hardcoded integer argument. The corresponding pseudo-random number generator generates a predictable sequence.

The work of many cryptographic algorithms is based on the use of cryptographically stable PRNG. Some algorithms take as an additional argument the seed value and for each value of this parameter generate a predictable sequence. In this case, the security of the system is based on the assumption that the seed values will be unpredictable.

Sensitive Data Exposure vulnerabilities take the third place in the “OWASP Top 10 2017” web-application vulnerabilities ranking.
