In this contract, 'bool sufficientAllowance = allowance <= _value' will cause an arbitrary transfer in the function transferFrom because '<=' is used instead of '>=' (which was intended). An attacker can transfer from any address to his address, and does not need to meet the 'allowance > value' condition.","published":"2018-07-16T02:29:01.000Z","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":["virgo zodiactoken project/virgo zodiactoken"],"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%).
