Background
Foreman-mcp-server is a component designed for managing and orchestrating cloud infrastructure. It provides functionalities such as resource provisioning, monitoring, and management of virtual machines. However, it has been identified to have vulnerabilities related to logging mechanisms that can expose sensitive information, such as session identifiers and authentication tokens, if not properly managed.
Vulnerability Detail
A flaw exists in foreman-mcp-server where two logging mechanisms can inadvertently expose sensitive session and authentication data. One mechanism logs session identifiers at an informational level, while the other, when debug logging is enabled, fails to adequately sanitize HTTP request headers. This results in sensitive information, including authorization tokens and API keys, being logged in cleartext. The implications of this vulnerability are significant, as it can lead to unauthorized access and a breach of confidentiality, especially if logs are forwarded to centralized logging platforms.
How To Fix
No fixed version is published for this vulnerability.

Workaround
As a temporary measure, you can disable debug logging to prevent sensitive information from being logged. This can typically be done by adjusting the logging configuration in your application settings to set the log level to 'INFO' or higher, thus avoiding the logging of sensitive data.
Conclusion
The vulnerability CVE-2026-9073 in foreman-mcp-server poses a risk of exposing sensitive information through inadequate logging mechanisms. It is crucial to update to the latest version to mitigate this risk and ensure the confidentiality of authentication data.
