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.
