Summary
openssl_encrypt before 1.4.9 KDF Downgrade via CWD-relative Configuration
Details

opensslencrypt (pip package openssl-encrypt) versions <= 1.4.8 contain a CWD-relative configuration file resolution flaw in cryptsettings.py, where CONFIGFILE (originally the absolute per-user path ~/.cryptsettings.json) is reassigned at line 84 to the bare relative name 'cryptsettings.json'. As a result, the legacy Tk GUI's SettingsTab reads and writes KDF settings from cryptsettings.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.
