CVE-2026-81716Hinoki check available

Cross-plugin file access via bare path prefix

Published Aug 27, 2026 · Updated Aug 27, 2026

Path traversal in jahlives OpenSSL Encrypt before 1.4.9 allows local users to read or write sibling plugin files. PluginSandbox._is_safe_path accepts any resolved path whose string begins with an allowed directory, without requiring a path-separator boundary. Exploitation requires control of a sandboxed plugin and a sibling directory with a shared name prefix, bypassing per-plugin isolation within the same user.
