CVE-2026-74895: openssl_encrypt before 1.4.0 allows malicious plugins full system access
CVE-2026-74895 · published 1 month ago
Summary
Versions of jahlives/openssl_encrypt released before 1.4.0 do not enforce the built‑in sandbox for plugin code. This lets a attacker run a crafted plugin that can read, modify, or delete files, use the network, start other programs, and import any Python module. Update to version 1.4.0 or later, or disable third‑party plugins until the fix is applied.
What to do
- Update jahlives openssl_encrypt to version 1.4.0 or later.

Original advisory text
openssl_encrypt before 1.4.0 Plugin Sandbox Bypass via Process Isolation
openssl_encrypt versions before 1.4.0 fail to apply sandbox restrictions in the default process isolation mode for plugin execution. Attackers can execute malicious plugins with unrestricted access to the filesystem, network, subprocess execution, and all Python modules.
