CVE-2026-74875

openssl_encrypt (Python package) before 1.4.0 silently skips JSON schema validation when the optional jsonschema library is absent, allowing attackers to remove that package or supply unknown metadata format versions to bypass all schema checks and process malicious data (CVSS 9.8 CRITICAL). No i...

opensslencrypt versions before 1.4.0 silently skip JSON schema validation when the jsonschema library is not installed, allowing malformed metadata to be accepted. Attackers can remove the jsonschema package or supply unknown metadata format versions to bypass all schema checks and process...

CVE-2026-74874 openssl_encrypt before 1.4.0 Weak PRNG Steganography Pixel Selection

opensslencrypt versions before 1.4.0 use Python's non-cryptographic random module for steganographic pixel selection in the generatepseudorandomsequence function. Attackers who know the password can recover the Mersenne Twister state from approximately 624 outputs and predict pixel locations...

CVE-2026-74873 openssl_encrypt before 1.4.0 Password Exposure via CLI Argument

opensslencrypt versions before 1.4.0 expose passwords passed via the --password CLI argument in process listings accessible to all system users. Attackers can read process arguments through ps aux or /proc/pid/cmdline to retrieve plaintext passwords and keystore passwords...

CVE-2026-74874

openssl_encrypt versions before 1.4.0 use Python's non-cryptographic random module (Mersenne Twister) for steganographic pixel selection in the generate_pseudorandom_sequence() function (openssl_encrypt/plugins/steganography/core/utils.py, lines 89–91). The Mersenne Twister state is recoverable f...

CVE-2026-74873

The openssl_encrypt tool (before v1.4.0) passes --password values as visible process arguments, retrievable by any local user via ps aux or /proc/[pid]/cmdline, exposing plaintext and keystore passwords. CVSS 5.5 (local) / 8.7 (network). Upgrade to v1.4.0 or pass passwords via stdin/env instead o...

CVE-2026-74872

The Python package openssl_encrypt before version 1.4.0 loads native .so modules via a broad glob pattern (whirlpool*py313*.so) without integrity checks, allowing arbitrary code execution. Attackers placing malicious .so files in site-packages trigger native code execution on module load. Fixed i...

CVE-2026-74872 openssl_encrypt before 1.4.0 Arbitrary Code Execution via Whirlpool

opensslencrypt versions before 1.4.0 contain an arbitrary code execution vulnerability in the Whirlpool hash implementation that uses broad glob patterns to load .so modules without integrity verification. Attackers can place malicious .so files matching the whirlpoolpy313.so pattern in...

CVE-2026-74870 openssl_encrypt before 1.4.8 Hardware Pepper Information Disclosure

opensslencrypt pip versions = 1.4.7 contain an information exposure vulnerability where the 'hsm fido2-test' and 'hsm onlykey-test' diagnostic commands unconditionally print the full derived hardware pepper as hex to stdout/stderr cryptcli.py, handlehsmcommand. The printed value can persist in...

CVE-2026-74871

The jahlives/openssl_encrypt PHP package before 1.4.6 has a KDF bypass: in sequential XOR composition mode the final stage cancels out, so attackers with local access can crack passwords at SHA-256 speed instead of the configured memory-hard KDF cost. CVSS 6.2 (MEDIUM, local). No in-the-wild expl...

EUVD-2026-60090

opensslencrypt versions before 1.4.6 contain a key derivation flaw in sequential XOR composition mode where the last stage cancels out during key generation.
