{"id":"CVE-2025-46653","details":"Formidable (aka node-formidable) 2.1.0 through 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":["GHSA-75v8-2h7p-7m2m"],"modified":"2026-08-12T03:51:25.392994830Z","published":"2025-04-26T00:00:00Z","related":["CGA-h2wp-88jr-8373"],"database_specific":{"cna_assigner":"mitre","cwe_ids":["CWE-338"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/46xxx/CVE-2025-46653.json"},"references":[{"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":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/46xxx/CVE-2025-46653.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-46653"},{"type":"FIX","url":"https://github.com/node-formidable/formidable/commit/022c2c5577dfe14d2947f10909d81b03b6070bf5"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/node-formidable/formidable","events":[{"introduced":"6da191c2eb926fbe5b146d67826ca9a8b8ddac0f"},{"fixed":"0bf31f65877fa1dce4c163c0f3a0e588afbbe45b"},{"fixed":"022c2c5577dfe14d2947f10909d81b03b6070bf5"}],"database_specific":{"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:node-formidable:formidable:*:*:*:*:*:node.js:*:*","extracted_events":[{"introduced":"2.1.0"},{"fixed":"3.5.3"}]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-46653.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"}]}
