{"apiVersion":"1.0","identifier":"CVE-2026-81700","description":"openssl_encrypt versions before 1.4.9 contain a signature verification vulnerability in gpg_runner.verify_detached that accepts revoked and expired keys by only checking VALIDSIG status without inspecting REVKEYSIG, EXPKEYSIG, or gpg exit codes. Attackers holding compromised-then-revoked signing keys or expired project keys can bypass signature verification to execute malicious plugins in the host process.","publishedAt":"2026-08-27T17:21:00","lastModifiedAt":"2026-08-27T20:18:53","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-81700","cvssScore":9.8,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00254,"riskScore":1,"affectedProduct":"openssl_encrypt","affectedVersions":"<1.4.9","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-81700","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-81700","en":"https://www.redsauce.net/en/cves/CVE-2026-81700","fr":"https://www.redsauce.net/fr/cves/CVE-2026-81700","pt":"https://www.redsauce.net/pt/cves/CVE-2026-81700","de":"https://www.redsauce.net/de/cves/CVE-2026-81700","sk":"https://www.redsauce.net/sk/cves/CVE-2026-81700","el":"https://www.redsauce.net/el/cves/CVE-2026-81700"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-81700"}}
