What is CVE-2026-30930?
CVE-2026-30930 is a high-severity SQL injection vulnerability in nicolargo glances, published on 10 Mar 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
Glances is an open-source system cross-platform monitoring tool. Prior to 4.5.1, The TimescaleDB export module constructs SQL queries using string concatenation with unsanitized system monitoring data. The normalize() method wraps string values in single quotes but does not escape embedded single quotes, making SQL injection trivial via attacker-controlled data such as process names, filesystem mount points, network interface names, or container names. This vulnerability is fixed in 4.5.1.
Weakness: CWE-89
