   "summary": "AugAssign evaluation order causing OOB write within the object in Vyper",
   "details": "Vyper handles AugAssign statements by first caching the target location to avoid double evaluation. However, in the case when target is an access to a DynArray and the rhs modifies the array, the cached target will evaluate first, and the bounds check will not be re-evaluated during the write portion of the statement. In other words, the following code\n\n```vyper\ndef poc():\n    a: DynArray[uint256, 2] = [1, 2]\n    a[1] += a.pop()\n```\n\nis equivalent to:\n```vyper\ndef poc():\n    a: DynArray[uint256, 2] = [1, 2]\n    a[1] += a[len(a) - 1]\n    a.pop()\n```\nrather than:\n```vyper\ndef poc():\n    a: DynArray[uint256, 2] = [1, 2]\n    s: uint256 = a[1]\n    t: uint256 = a.pop()\n    a[1] = s + t  # reverts due to oob access\n```",
