Two chained authentication bypass vulnerabilities in the Qinglong open-source task scheduler are being actively exploited to install cryptomining software on affected servers. Organizations running Qinglong versions 2.20.1 or older with internet-exposed panels are at direct risk; exploitation began February 7, 2026, weeks before public disclosure. The primary business impact is server resource theft, potential lateral movement from compromised hosts, and operational disruption if affected systems run production workloads.
