When the own identity is deleted, the shadowed contact becomes visible and resolves to the attacker's keys, enabling silent key substitution for encrypted files.","state":0,"publishedAt":"2026-08-27T14:51:08.461+00:00","modifiedAt":"2026-10-01T15:21:33.701+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:H/VA:H/SC:N/SI:N/SA:N","score":9.3,"severity":"CRITICAL"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:N","score":6.8,"severity":"MEDIUM"}],"references":["https://github.com/jahlives/openssl_encrypt/security/advisories/GHSA-8gmx-w9m8-vx7q","https://www.vulncheck.com/advisories/openssl-encrypt-before-1.4.9-key-substitution-via-identity-shadowing"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-81706","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-81706","identifiers":["CVE-2026-81706"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
