{"apiVersion":"1.0","identifier":"CVE-2026-81697","description":"openssl_encrypt (pip package openssl-encrypt) versions <= 1.4.8 contain a CWD-relative configuration file resolution flaw in crypt_settings.py, where CONFIG_FILE (originally the absolute per-user path ~/.crypt_settings.json) is reassigned at line 84 to the bare relative name -crypt_settings.json-. As a result, the legacy Tk GUI-s SettingsTab reads and writes KDF settings from crypt_settings.json in the process launch (current working) directory instead of the user-s home directory. An attacker who plants a malicious crypt_settings.json (e.g. sha256:1 with all memory-hard KDFs disabled) can silently downgrade encryption performed in that GUI session to roughly one hash round, bypassing the weak-KDF preflight and enabling offline brute-force attacks against the resulting ciphertext. Fixed in 1.4.9.","publishedAt":"2026-08-27T17:20:59","lastModifiedAt":"2026-08-27T17:20:59","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-81697","cvssScore":5.5,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N","epssProbability":0.00149,"riskScore":0.56,"affectedProduct":"openssl_encrypt","affectedVersions":"<=1.4.8","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-81697","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-81697","en":"https://www.redsauce.net/en/cves/CVE-2026-81697","fr":"https://www.redsauce.net/fr/cves/CVE-2026-81697","pt":"https://www.redsauce.net/pt/cves/CVE-2026-81697","de":"https://www.redsauce.net/de/cves/CVE-2026-81697","sk":"https://www.redsauce.net/sk/cves/CVE-2026-81697","el":"https://www.redsauce.net/el/cves/CVE-2026-81697"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-81697"}}
