{"apiVersion":"1.0","identifier":"CVE-2026-81699","description":"openssl_encrypt versions before 1.4.9 fail to properly validate key derivation function costs in crafted files, allowing attackers to trigger unbounded memory and CPU exhaustion during pre-authentication processing. Attackers can supply malicious files with excessive KDF parameters to exhaust system resources and crash or wedge the process before password verification occurs.","publishedAt":"2026-08-27T17:21:00","lastModifiedAt":"2026-08-27T17:21:00","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-81699","cvssScore":7.5,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","epssProbability":0.00353,"riskScore":0.77,"affectedProduct":"openssl_encrypt","affectedVersions":"<1.4.9","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-81699","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-81699","en":"https://www.redsauce.net/en/cves/CVE-2026-81699","fr":"https://www.redsauce.net/fr/cves/CVE-2026-81699","pt":"https://www.redsauce.net/pt/cves/CVE-2026-81699","de":"https://www.redsauce.net/de/cves/CVE-2026-81699","sk":"https://www.redsauce.net/sk/cves/CVE-2026-81699","el":"https://www.redsauce.net/el/cves/CVE-2026-81699"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-81699"}}
