CVE-2025-65681 affects Overhang.IO Tutor (overhangio/tutor) version 20.0.2 and earlier. The issue is described as sensitive information disclosure caused by the absence of proper Cache-Control HTTP headers together with missing client-side session checks. In this condition, sensitive application content can remain accessible from client-side or intermediary caches even when it should no longer be available to an unauthorized local user. Based on the available information, the vulnerability is an information exposure issue rather than code execution, but specific affected endpoints or functions are not provided in the source content.
