Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

（pip 包名： ）1.4.9 之前的版本中， 函数存在一个路径遍历漏洞，该漏洞使用简单的字符串前缀匹配来授权文件访问。这意味着一个未被授予 权限的沙箱插件，可能读取或写入另一个仅共享名称前缀的插件目录（例如，允许访问 ，而 会因前缀匹配而被误判为合法路径），从而破坏了同一用户内插件之间的隔离性。 该问题已通过修改匹配逻辑得到修复：现在要求对每个允许的目录进行精确匹配，或在路径末尾添加路径分隔符（如 ），以彻底避免前缀误匹配。

Vulnerability Title
openssl_encrypt before 1.4.9 Plugin Sandbox Path Traversal
Source: CVE Program / CVE List V5
Vulnerability 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.
