CVE-2026-32609 in glances
Summary
by MITRE • 03/18/2026
Glances is an open-source system cross-platform monitoring tool. The GHSA-gh4x fix (commit 5d3de60) addressed unauthenticated configuration secrets exposure on the `/api/v4/config` endpoints by introducing `as_dict_secure()` redaction. However, the `/api/v4/args` and `/api/v4/args/{item}` endpoints were not addressed by this fix. These endpoints return the complete command-line arguments namespace via `vars(self.args)`, which includes the password hash (salt + pbkdf2_hmac), SNMP community strings, SNMP authentication keys, and the configuration file path. When Glances runs without `--password` (the default), these endpoints are accessible without any authentication. Version 4.5.2 provides a more complete fix.

CVE-2026-32609 represents a critical configuration secrets exposure vulnerability within the Glances system monitoring tool that demonstrates poor security practices in API endpoint design and authentication handling. This vulnerability specifically affects the `/api/v4/args` and `/api/v4/args/{item}` endpoints, which were inadvertently left unprotected during a previous security fix for similar issues in the `/api/v4/config` endpoint. The flaw stems from the tool's default behavior of exposing command-line argument namespaces through these endpoints without requiring authentication, creating a significant attack surface that could be exploited by unauthorized parties.
The technical implementation of this vulnerability involves the direct exposure of sensitive configuration data through the `vars(self.args)` function call, which returns the complete argument namespace containing critical security information. This includes password hash components consisting of salt values combined with pbkdf2_hmac hashes, SNMP community strings that provide network access credentials, SNMP authentication keys that enable privileged network operations, and the full configuration file path that could reveal system structure and potentially sensitive deployment information. The vulnerability directly maps to CWE-200 (Information Exposure) and CWE-312 (Sensitive Data Exposure) categories, as it exposes confidential information through improperly protected API endpoints.
The operational impact of this vulnerability is substantial as it allows any unauthenticated attacker to gain access to sensitive system configuration data that would normally be protected. When Glances runs without the `--password` flag, which is the default configuration, these endpoints become completely accessible to external parties. This exposure could enable attackers to perform credential stuffing attacks against SNMP services, potentially gain unauthorized network access, or leverage the configuration file path to conduct further reconnaissance. The vulnerability also aligns with ATT&CK technique T1528 (Credentials in Files) and T1083 (File and Directory Discovery) as it exposes both credential information and system configuration paths.
The remediation approach requires careful attention to authentication requirements and data sanitization practices for all API endpoints. The complete fix implemented in version 4.5.2 addresses not only the previously identified configuration endpoint but also extends protection to the argument endpoints through proper authentication enforcement. Organizations should ensure that all API endpoints in monitoring tools implement appropriate authentication mechanisms, particularly those that expose system configuration data. The fix should include mandatory authentication for all configuration-related endpoints and proper data sanitization that prevents exposure of sensitive information even when endpoints are accessed by authorized users. Security teams should also implement network segmentation and monitoring of API access patterns to detect potential exploitation attempts against such endpoints.
