CVE-2026-68520: CWE-200: Exposure of Sensitive Information to an Unauthorized Actor in nicolargo glances
CVE-2026-68520 is a medium severity vulnerability in the open-source system monitoring tool Glances. Versions prior to 4.5.6 have a flaw in the as_dict_secure() function in glances/config.py, which insufficiently checks option names and inadvertently exposes sensitive information such as public_username and credentials embedded in public_api values. This exposure occurs via unauthenticated GET requests to /api/4/config and /api/4/config/ip endpoints. The issue has been fixed in version 4.5.6.
AI Analysis
Technical Summary
Glances versions before 4.5.6 contain an information exposure vulnerability (CWE-200) due to inadequate filtering in the as_dict_secure() function. This allows unauthenticated users to retrieve sensitive data including public_username and credentials embedded in public_api configuration values through specific API endpoints. The vulnerability is addressed by the fix implemented in version 4.5.6.
Potential Impact
An unauthenticated attacker can access sensitive information such as usernames and credentials by sending GET requests to the affected API endpoints. This exposure could potentially lead to further attacks if the leaked credentials are reused or provide access to other systems. The impact is limited to information disclosure without direct integrity or availability effects.
Mitigation Recommendations
Upgrade Glances to version 4.5.6 or later, where this vulnerability is fixed. No other mitigation is required as the issue is resolved by the official patch.
