CVE-2026-74900

opensslencrypt versions before 1.4.0 contain a critical vulnerability in pqc.py where KEM decapsulation failures silently fall back to simulation mode, generating a deterministic shared secret from only 16 bytes of the private key and publicly available encapsulated key data. Attackers who obtain...

CVE-2026-74901

The Python package openssl_encrypt (versions before 1.4.0) has a flaw in pqc.py : when AES-GCM decryption fails, the code silently falls back to unauthenticated AES-CTR mode. This removes integrity verification, allowing an attacker with network access to modify ciphertext in transit via bit-flip...

CVE-2026-74899

openssl_encrypt (versions before 1.4.0) has a sandbox escape in its IsolatedPluginExecutor component. Restricted exec() builtins expose Python type objects, allowing attackers to traverse the class hierarchy via __class__.__mro__.__subclasses__() to reach system functions and run arbitrary OS com...

CVE-2026-74896

The Python package openssl_encrypt before 1.4.0 ships a DangerousPatternVisitor AST analyzer intended to block dangerous code in plugin scripts, but it fails to recognize dunder attribute traversal chains (__class__, __bases__, __subclasses__(), __globals__). Attackers can use these chains to rea...

CVE-2026-74895

openssl_encrypt (Python package) versions before 1.4.0 fail to apply sandbox restrictions in the default process isolation mode for plugin execution, allowing attackers to run malicious plugins with unrestricted filesystem, network, subprocess, and Python module access (CVSS 9.8 CRITICAL). No in-...

CVE-2026-74896 openssl_encrypt before 1.4.0 Sandbox Escape via Dunder Attribute Traversal

opensslencrypt versions before 1.4.0 contain a sandbox escape vulnerability in the DangerousPatternVisitor AST analyzer that fails to detect dunder attribute traversal techniques. Attackers can use class, bases, subclasses, and globals chains to access restricted functions and execute arbitrary...
