CVE-2018-14089 is a high-severity flaw (CVSS 7.5) affecting virgo zodiactoken. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

An issue was discovered in a smart contract implementation for Virgo_ZodiacToken, an Ethereum token. In this contract, 'bool sufficientAllowance = allowance <= _value' will cause an arbitrary transfer in the function transferFrom because '<=' is used instead of '>=' (which was intended). An attacker can transfer from any address to his address, and does not need to meet the 'allowance > value' condition.
