{"id":"GHSA-75v8-2h7p-7m2m","summary":"Formidable relies on hexoid to prevent guessing of filenames for untrusted executable content","details":"Formidable (aka node-formidable) 2.x before 2.1.3 and 3.x before 3.5.3 relies on hexoid to prevent guessing of filenames for untrusted executable content; however, hexoid is documented as not \"cryptographically secure.\" (Also, there is a scenario in which only the last two characters of a hexoid string need to be guessed, but this is not often relevant.) NOTE: this does not imply that, in a typical use case, attackers will be able to exploit any hexoid behavior to upload and execute their own content.","aliases":["CVE-2025-46653"],"modified":"2026-07-17T21:12:03.168533432Z","published":"2025-04-26T21:31:26Z","database_specific":{"nvd_published_at":"2025-04-26T21:15:14Z","cwe_ids":["CWE-338"],"severity":"LOW","github_reviewed":true,"github_reviewed_at":"2025-04-29T14:07:17Z"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-46653"},{"type":"WEB","url":"https://github.com/node-formidable/formidable/commit/022c2c5577dfe14d2947f10909d81b03b6070bf5"},{"type":"WEB","url":"https://github.com/node-formidable/formidable/commit/37a3e89fca1ed68ec674a539f13aafd62221ddaa"},{"type":"PACKAGE","url":"https://github.com/node-formidable/formidable"},{"type":"WEB","url":"https://github.com/node-formidable/formidable/blob/d0fbec13edc8add54a1afb9ce1a8d3db803f8d47/CHANGELOG.md?plain=1#L10"},{"type":"WEB","url":"https://github.com/zast-ai/vulnerability-reports/blob/main/formidable/file_upload/report.md"},{"type":"WEB","url":"https://www.npmjs.com/package/formidable/v/2.1.3"},{"type":"WEB","url":"https://www.npmjs.com/package/formidable/v/3.5.3"}],"affected":[{"package":{"name":"formidable","ecosystem":"npm","purl":"pkg:npm/formidable"},"ranges":[{"type":"SEMVER","events":[{"introduced":"3.1.1-canary.20211030"},{"fixed":"3.5.3"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/04/GHSA-75v8-2h7p-7m2m/GHSA-75v8-2h7p-7m2m.json"}},{"package":{"name":"formidable","ecosystem":"npm","purl":"pkg:npm/formidable"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.1.0"},{"fixed":"2.1.3"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/04/GHSA-75v8-2h7p-7m2m/GHSA-75v8-2h7p-7m2m.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:N"}]}
