Findings

  • medium Arithmetic without overflow checks
    The code targets Solidity below 0.8 and does arithmetic without SafeMath, so overflows wrap silently.
  • medium Outdated Solidity compiler
    Compiled with Solidity 0.5.16, which predates built-in overflow checks and later compiler bug fixes.
  • medium Privileged mint function
    An owner or role can mint new tokens.
  • low Raw ecrecover
    Signatures are checked with raw ecrecover, which allows malleable signatures and returns zero on bad input.

Evidence, exact locations and fixes are in the deep report. How scoring works.
