CVE-2026-81716

openssl_encrypt before 1.4.9 Plugin Sandbox Path Traversal

Published Aug 27, 2026 CVSS 4.0 · 8.7 High EPSS < 1% KEV · Not listed
Description
openssl_encrypt (pip: openssl-encrypt) versions before 1.4.9 contain a path traversal flaw in PluginSandbox._is_safe_path, which authorized file access using a bare string-prefix match. A sandboxed plugin without the READ_FILES permission could read or write another plugin's directory that merely shares a name prefix (e.g., .../plugins/foobar matching allowed .../plugins/foo), breaking per-plugin isolation within the same user. Fixed by matching each allowed directory exactly or with a trailing path separator.
