# CVE-2026-35587

> Vulnerability · severity: **HIGH** (CVSS 8.8).

## Description

Glances is an open-source system cross-platform monitoring tool. Prior to version 4.5.4, a Server-Side Request Forgery (SSRF) vulnerability exists in the Glances IP plugin due to improper validation of the public_api configuration parameter. The value of public_api is used directly in outbound HTTP requests without any scheme restriction or hostname/IP validation. An attacker who can modify the Glances configuration can force the application to send requests to arbitrary internal or external endpoints. Additionally, when public_username and public_password are set, Glances automatically includes these credentials in the Authorization: Basic header, resulting in credential leakage to attacker-controlled servers. This vulnerability can be exploited to access internal network services, retrieve sensitive data from cloud metadata endpoints, and/or exfiltrate credentials via outbound HTTP requests. The issue arises because public_api is passed directly to the HTTP client (urlopen_auth) without validation, allowing unrestricted outbound connections and unintended disclosure of sensitive information. Version 4.5.4 contains a patch.
