Most Logrus deployments do not expose this interface directly to attacker-controlled input, which raises the attack complexity and reduces realistic exploitability. Additionally, the flaw does not affect confidentiality or integrity, nor does it allow code execution or privilege escalation. The failure results in a controlled degradation of availability (logging becoming non-functional), rather than a broader application outage or systemic compromise. These constrained conditions and limited real-world impact justify treating the issue as moderate rather than important.",
