(Increasing the total supply by using 'doAirdrop' ignores the hard cap written in the contract and devalues the token.)","published":"2019-06-19T16:15:11.000Z","lastModified":"2026-06-17T01:47:17.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.0","score":6.5,"severity":"MEDIUM","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N"},"cwe":["CWE-330"],"affected":["primeo project/primeo"],"epss":{"score":0.01065,"percentile":0.64567,"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":"low","text":"Lower severity and a low EPSS score (1.06%).
