{"apiVersion":"1.0","identifier":"CVE-2026-81719","description":"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.","publishedAt":"2026-08-27T17:21:02","lastModifiedAt":"2026-08-27T20:18:54","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-81719","cvssScore":7.8,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","epssProbability":0.00316,"riskScore":0.8,"affectedProduct":"openssl-encrypt","affectedVersions":"<1.4.9","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-81719","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-81719","en":"https://www.redsauce.net/en/cves/CVE-2026-81719","fr":"https://www.redsauce.net/fr/cves/CVE-2026-81719","pt":"https://www.redsauce.net/pt/cves/CVE-2026-81719","de":"https://www.redsauce.net/de/cves/CVE-2026-81719","sk":"https://www.redsauce.net/sk/cves/CVE-2026-81719","el":"https://www.redsauce.net/el/cves/CVE-2026-81719"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-81719"}}
