EUVD-2026-60109

opensslencrypt versions before 1.4.0 contain an authentication bypass vulnerability in CamelliaCipher that disables HMAC tag generation and verification when the PYTESTCURRENTTEST environment variable is set. Attackers with code execution can set this environment variable to produce unauthenticat...

CVE-2026-74889 openssl_encrypt before 1.4.0 Weak Key Derivation via HKDF

opensslencrypt versions before 1.4.0 use HKDF with no salt and static info parameter in key normalization functions, reducing entropy extraction and determinism. Attackers can exploit predictable key derivation with identical inputs to weaken cryptographic security against multi-target attacks...

CVE-2026-74889

The openssl_encrypt library (PHP package) before version 1.4.0 uses HKDF with no salt and a static info parameter in its key normalization functions, producing deterministic, low-entropy derived keys. Attackers with identical inputs can predict derived keys, weakening cryptographic security again...

CVE-2026-74890

openssl_encrypt versions before 1.4.0 have an authentication bypass in the CamelliaCipher component: setting the PYTEST_CURRENT_TEST environment variable disables HMAC tag generation and verification, allowing attackers with code execution to produce unauthenticated ciphertext and bypass integrit...

CVE-2026-74888

The PHP package openssl_encrypt before 1.4.0 uses a non-standard PBKDF2 construction (iterations=1 per call) that weakens key derivation, enabling attackers to more efficiently crack passwords protecting legacy encrypted files. No in-the-wild exploitation is reported; upgrading to version 1.4.0 i...

CVE-2026-74888 openssl_encrypt before 1.4.0 Non-Standard PBKDF2 Key Derivation

opensslencrypt versions before 1.4.0 use a non-standard PBKDF2 key derivation construction with iterations=1 per call in an outer loop, creating a KDF whose security properties have not been formally analyzed. Attackers can exploit this weakened key derivation to more efficiently crack passwords...

CVE-2026-74887 openssl_encrypt before 1.4.0 Insecure Random Import in PQC Module

opensslencrypt before 1.4.0 imports Python's non-cryptographic 'random' module Mersenne Twister PRNG at line 15 of opensslencrypt/modules/pqc.py. No direct calls to random. were present in the code, so no cryptographic operation is currently affected; however, the import creates a hazard that...

EUVD-2026-60105

opensslencrypt versions before 1.4.0 contain a plugin sandbox bypass vulnerability where the PluginImportGuard blocks a different set of modules than the AST analyzer's DANGEROUSMODULES set. Attackers can bypass AST analysis through string obfuscation or encoding to import unblocked dangerous...

opensslencrypt before 1.4.0 imports Python's non-cryptographic 'random' module Mersenne Twister PRNG at line 15 of opensslencrypt/modules/pqc.py. No direct calls to random. were present in the code, so no cryptographic operation is currently affected; however, the import creates a hazard that...

CVE-2026-74886 openssl_encrypt before 1.4.0 Plugin Import Guard Bypass

opensslencrypt versions before 1.4.0 contain a plugin sandbox bypass vulnerability where the PluginImportGuard blocks a different set of modules than the AST analyzer's DANGEROUSMODULES set. Attackers can bypass AST analysis through string obfuscation or encoding to import unblocked dangerous...

CVE-2026-74886

In openssl_encrypt before 1.4.0, PluginImportGuard blocks a different module set than the AST analyzer's DANGEROUS_MODULES, allowing attackers to bypass AST checks via string obfuscation and import modules like sys, pickle, or multiprocessing for arbitrary code execution. CVSS 9.8 critical. No in...

CVE-2026-74887

openssl_encrypt before 1.4.0 imports Python's non-cryptographic random module (Mersenne Twister) in modules/pqc.py line 15. No current code calls random.*, so no crypto operation is actively affected, but the import creates a latent hazard: future code could accidentally use predictable PRNG outp...
