**Name of the Vulnerable Software and Affected Versions** pistacheio/pistache versions prior to 0.0.3.20220425 **Description** The issue allows directory traversal, enabling the fetching of arbitrary files from the server. This is a significant security concern as it could lead to unauthorized access to sensitive data. **Recommendations** For versions prior to 0.0.3.20220425, update to version 0.0.3.20220425 or later to resolve the issue. As a temporary workaround, consider restricting access to sensitive files and directories on the server to minimize the risk of exploitation.

Name of the Vulnerable Software and Affected Versions: github.com/kataras/iris versions prior to a fixed version github.com/kataras/iris/v12 versions prior to a fixed version Description: The issue arises from the unsafe handling of file names during upload using the `UploadFormFiles` method, which may enable attackers to write to arbitrary locations outside the designated target folder. This vulnerability can be exploited through directory traversal attacks. The `Context.UploadFormFiles` function is specifically vulnerable to this type of attack. It is noted that this issue is mitigated in Go versions 1.17 and later, as they strip directory paths from filenames returned by `mime/multipart`.Part.FileName. Recommendations: For github.com/kataras/iris versions prior to a fixed version, consider disabling the `UploadFormFiles` method until a patch is available. For github.com/kataras/iris/v12 versions prior to a fixed version, consider disabling the `UploadFormFiles` method until a patch is available. As a temporary workaround, restrict the handling of file uploads to prevent writing to arbitrary locations outside the designated target folder.
