| Title | leomoon-studios wiki-go <= 1.9.1 Path Traversal |
|---|
| Description | wiki-go ≤ 1.9.1 contains a path-traversal flaw in the DeleteCommentHandler (admin-only) that allows an authenticated administrator to delete arbitrary files on the host filesystem by submitting a crafted documentPath segment in the request URL. The vulnerability is rooted in internal/comments/comments.go (DeleteComment) which concatenates the URL-derived path into os.Remove without any filepath.Clean or SanitizePath validation; DeleteCommentHandler only validates the trailing commentID against a loose regex (^\d{14}_[\w-]+\.md$), not the documentPath. The flaw affects all default deployments (admin role, default credentials admin/admin). |
