{"id":"CVE-2026-81680","summary":"openssl_encrypt before 1.4.9 Authentication Bypass via Recovery Slot Removal","details":"openssl_encrypt versions before 1.4.9 fail to authenticate recovery-slot presence in envelope-format encrypted files, allowing attackers to remove recovery slots without re-encrypting the payload. Attackers can modify the file header to delete recovery-slot fields and bypass authentication, silently removing recovery paths the owner deliberately added.","aliases":["GHSA-grhj-cpmg-f5mx"],"modified":"2026-08-30T03:30:46.924719602Z","published":"2026-08-27T14:50:46.683Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/81xxx/CVE-2026-81680.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-347"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/81xxx/CVE-2026-81680.json"},{"type":"ADVISORY","url":"https://github.com/jahlives/openssl_encrypt/security/advisories/GHSA-grhj-cpmg-f5mx"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-81680"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openssl-encrypt-before-1.4.9-authentication-bypass-via-recovery-slot-removal"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/jahlives/openssl_encrypt","events":[{"introduced":"0"},{"fixed":"39b0a010cae90520f74b7194f61fedd43af04ef8"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.4.9"}],"source":["AFFECTED_FIELD","DESCRIPTION"]}}],"versions":["v1.4.7","v1.4.6","v1.4.5","v1.4.4","v1.4.2","v1.4.1rc2","v1.4.1rc1","v1.4.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-81680.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
