## Technical details

A path traversal vulnerability exists in the 'POST /api/extensions/delete' endpoint (and several related endpoints) due to improper input validation. The application uses the 'sanitize-filename' library, which converts a single dot (".") into an empty string. When this empty string is passed to 'path.join(basePath, "")', it resolves to the 'basePath' itself—the root extensions directory. Because the application performs a recursive deletion ('fs.promises.rm' with 'recursive: true') on the resulting path, an attacker can wipe the entire extensions folder. This requires no authentication in default configurations and can be exploited via a single HTTP request. The issue is fixed in version 1.18.0 by validating the input after sanitization.
