First, suppose that the owner adds the evil contract address to his sweepers. The evil contract looks like this: contract Exploit { uint public start; function sweep(address _token, uint _amount) returns (bool) { start = 0x123456789; return true;} }. Then, when one calls the function sweep() in the UserWallet contract, it will change the sweeperList to 0X123456789.","published":"2018-07-16T02:29:00.000Z","lastModified":"2026-06-17T01:40:38.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.0","score":7.5,"severity":"HIGH","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"},"cwe":["CWE-20"],"affected":["userwallet project/userwallet"],"epss":{"score":0.00926,"percentile":0.60292,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.93%).
