Executive Summary

The vulnerability exists in jotty·page, a self-hosted app for checklists and notes, in versions prior to 1.22.0. It is an unauthenticated path traversal vulnerability in the /api/app-icons/[filename] endpoint. The filename parameter is used directly to form a filesystem path without proper validation to prevent traversal outside the intended directory. This allows an attacker to read files outside the data/uploads/app-icons/ directory.

Impact Analysis

This vulnerability can allow an unauthenticated attacker to read arbitrary files on the server outside the intended directory. This could lead to exposure of sensitive information, such as configuration files, credentials, or other private data stored on the server. The CVSS score of 8.2 indicates a high severity impact with high confidentiality impact and low integrity impact.

Mitigation Strategies

To mitigate this vulnerability, upgrade jotty·page to version 1.22.0 or later, where the unauthenticated path traversal issue in /api/app-icons/[filename] has been fixed.
