An issue was discovered in a smart contract implementation for MKCB, an Ethereum token. If the owner sets the value of sellPrice to a large number in setPrices() then the "amount * sellPrice" will cause an integer overflow in sell().

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
