EUVD-2026-60092

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...

EUVD-2026-60093

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

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-2026-74873 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-2026-74872 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-2026-74872

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-2026-74871

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...

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...

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. When configured with a single KDF and no prior hashing stage, attackers can bypass memory-hard key derivation and perform offline password...

CVE-2026-74871 openssl_encrypt before 1.4.6 KDF Bypass via Sequential-XOR

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. When configured with a single KDF and no prior hashing stage, attackers can bypass memory-hard key derivation and perform offline password...

Oracle Linux 8 : php:7.4 (ELSA-2026-47750)

The remote Oracle Linux 8 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2026-47750 advisory. libzip php 7.4.33-5 - Fix Memory corruption zendmmheap corrupted in opensslencrypt with AES-WRAP-PAD CVE-2026-14355 php-pear php-pecl-apcu php-pecl-rrd...

php: ext/openssl: memory corruption in openssl_encrypt with AES-WRAP-PAD

A flaw was found in the OpenSSL extension of PHP. The AES-WRAP-PAD algorithm implementation uses the size of the plaintext length without accounting for the RFC 5649 expansion to allocate the output buffer for the AES key-wrap-with-padding operation. This may lead to an undersized memory allocati...

BIT-PHP-MIN-2020-7069 Wrong ciphertext/tag in AES-CCM encryption for a 12 bytes IV

In PHP versions 7.2.x below 7.2.34, 7.3.x below 7.3.23 and 7.4.x below 7.4.11, when AES-CCM mode is used with opensslencrypt function with 12 bytes IV, only first 7 bytes of the IV is actually used. This can lead to both decreased security and incorrect encryption data...
