CVE-2018-12975: Cryptosaga

High severity, CVSS 7.5. EPSS: 1.3% chance of exploitation in the next 30 days.

The random() function of the smart contract implementation for CryptoSaga, an Ethereum game, generates a random value with publicly readable variables such as timestamp, the current block's blockhash, and a private variable (which can be read with a getStorageAt call). Therefore, attackers can precompute the random number and manipulate the game (e.g., get powerful characters or get critical damages).
