{"id":"GHSA-3839-6r69-m497","summary":"Duplicate Advisory: GoUtils's randomly-generated alphanumeric strings contain significantly less entropy than expected","details":"## Duplicate Advisory\nThis advisory has been withdrawn because it is a duplicate of GHSA-xg2h-wx96-xgxr. This link is maintained to preserve external references.\n\n## Original Description\nRandomly-generated alphanumeric strings contain significantly less entropy than expected. The `RandomAlphaNumeric` and `CryptoRandomAlphaNumeric` functions always return strings containing at least one digit from 0 to 9. This significantly reduces the amount of entropy in short strings generated by these functions.","aliases":["CVE-2021-4238","GHSA-xg2h-wx96-xgxr","GO-2022-0411"],"modified":"2026-07-17T21:12:37.784877177Z","published":"2022-12-28T00:30:23Z","withdrawn":"2026-01-23T22:51:27Z","database_specific":{"nvd_published_at":"2022-12-27T22:15:00Z","cwe_ids":["CWE-331"],"severity":"CRITICAL","github_reviewed":true,"github_reviewed_at":"2022-12-30T18:53:53Z"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-4238"},{"type":"WEB","url":"https://github.com/Masterminds/goutils/commit/869801f20f9f1e7ecdbdb6422049d8241270d5e1"},{"type":"PACKAGE","url":"https://github.com/Masterminds/goutils"},{"type":"WEB","url":"https://pkg.go.dev/vuln/GO-2022-0411"}],"affected":[{"package":{"name":"github.com/Masterminds/goutils","ecosystem":"Go","purl":"pkg:golang/github.com/Masterminds/goutils"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.1.1"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/12/GHSA-3839-6r69-m497/GHSA-3839-6r69-m497.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H"}]}
