Detailsinfo

A vulnerability was found in Wheels up to 4.1.1. It has been declared as problematic. This vulnerability affects an unknown code of the component Host Header Handler. The manipulation of the argument Host with an unknown input leads to a information disclosure vulnerability. The CWE definition for the vulnerability is CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. As an impact it is known to affect confidentiality. CVE summarizes:

Wheels through 4.1.1 derives its default production error-email address from the Host header of the request that starts the application. If no explicit error-email recipient is configured, a mail server is configured, and the server accepts an attacker-chosen Host, an attacker whose request triggers a cold start can direct later error emails to an address under their control for that application's lifetime. Emails disclose error and request metadata; on engines/versions where scope dumps render, they may also disclose configuration secrets and other users' session/cookie data. On the Lucee 7 engine, scope dumps fail to render, limiting disclosure to header fields. This is fixed in 4.1.2.

The advisory is available at github.com. This vulnerability was named CVE-2026-111450 since 10/16/2026. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1592 by the MITRE ATT&CK project.

Upgrading to version 4.1.2 eliminates this vulnerability.
