The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

vyper is a Pythonic Smart Contract Language for the EVM.
Affected versions of this package are vulnerable to Always-Incorrect Control Flow Implementation. The order of evaluation of the arguments of the builtin functions uint256_addmod
, uint256_mulmod
, ecadd
and ecmul
does not follow source order.
For uint256_addmod(a,b,c)
and uint256_mulmod(a,b,c)
, the order is c,a,b
.
For ecadd(a,b)
and ecmul(a,b)
, the order is b,a
.
Note:
This behaviour is problematic when the evaluation of one of the arguments produces side effects that other arguments depend on.
Mitigation:
When using builtins from the list above, users need to make sure that the arguments of the expression do not produce side effects or, if one does, that no other argument is dependent on those side effects.
