{"apiVersion":"1.0","identifier":"CVE-2026-74888","description":"openssl_encrypt versions before 1.4.0 use a non-standard PBKDF2 key derivation construction with iterations=1 per call in an outer loop, creating a KDF whose security properties have not been formally analyzed. Attackers can exploit this weakened key derivation to more efficiently crack passwords protecting legacy encrypted files compared to standard PBKDF2 implementations.","publishedAt":"2026-08-17T11:16:43","lastModifiedAt":"2026-08-17T13:16:53","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74888","cvssScore":7.5,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","epssProbability":0.00167,"riskScore":0.76,"affectedProduct":"openssl_encrypt","affectedVersions":"<1.4.0","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74888","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74888","en":"https://www.redsauce.net/en/cves/CVE-2026-74888","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74888","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74888","de":"https://www.redsauce.net/de/cves/CVE-2026-74888","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74888","el":"https://www.redsauce.net/el/cves/CVE-2026-74888"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74888"}}
