On Windows, Echo’s middleware.Static using the default filesystem allows path traversal via backslashes, enabling unauthenticated remote file read outside the static root.
Due to improper sanitization of user input on Windows, the static file handler allows for directory traversal, allowing an attacker to read files outside of the target directory that the server has permission to read.
Labstack Echo v4.8.0 was discovered to contain an open redirect vulnerability via the Static Handler component. This vulnerability can be leveraged by attackers to cause a Server-Side Request Forgery (SSRF).
This advisory has been marked as False Positive and removed.
