Attackers can perform offline password guessing against encrypted files roughly six to seven orders of magnitude faster than documented protection by exploiting the missing key stretching and hash rounds.","state":0,"publishedAt":"2026-08-27T14:51:06.96+00:00","modifiedAt":"2026-10-01T15:21:32.379+00:00","affected":[{"ecosystem":"Vendor product","name":"openssl_encrypt","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"jahlives\",\n                    \"product\": \"openssl_encrypt\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"packageURL\": \"pkg:pypi/openssl-encrypt\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"1.4.9\"\n                        },\n                        {\n                            \"version\": \"1.4.9\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":8.7,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5,"severity":"HIGH"}],"references":["https://github.com/jahlives/openssl_encrypt/security/advisories/GHSA-v9r6-grch-fxw7","https://www.vulncheck.com/advisories/openssl-encrypt-before-1.4.9-weak-key-derivation-via-d-bus"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-81704","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-81704","identifiers":["CVE-2026-81704"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
