CVE-2026-81716
MediumCVSS 5.2Summary
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.
Risk Assessment
The risk includes breaking isolation between plugins, which could allow a malicious plugin to access data of other plugins. This could lead to unauthorized file read or write.
Recommendation
It is recommended to update openssl_encrypt to version 1.4.9 or later, which includes the fix. Also review plugin permission configuration.
