{"id":"CVE-2026-81719","summary":"openssl_encrypt before 1.4.9 Remote Code Execution via Plugin","details":"openssl_encrypt before 1.4.9 executes untrusted third-party plugins with insufficient controls: the plugin signature policy defaulted to WARN, so an unsigned/unverifiable non-built-in plugin was compiled and executed in the host process at import time, before the runtime sandbox is installed. The only default gate was an incomplete, bypassable AST denylist. If a user is induced to load an attacker's plugin, this results in arbitrary code execution with the privileges of the user running openssl_encrypt. Fixed in 1.4.9 by defaulting the signature policy to ENFORCE for non-built-in plugins.","aliases":["GHSA-587j-4r3v-cm2c"],"modified":"2026-08-30T03:30:22.046737466Z","published":"2026-08-27T14:51:13.632Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/81xxx/CVE-2026-81719.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-94"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/81xxx/CVE-2026-81719.json"},{"type":"ADVISORY","url":"https://github.com/jahlives/openssl_encrypt/security/advisories/GHSA-587j-4r3v-cm2c"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-81719"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openssl-encrypt-before-1.4.9-remote-code-execution-via-plugin"}],"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-2026-81719.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"}]}
