THE NEWS

What happened

Verified reporting in clear, practical language.

Cybersecurity and Infrastructure Security Agency (CISA) has added five security flaws impacting JFrog Artifactory, ConnectWise ScreenConnect, and MikroTik RouterOS to its Known Exploited Vulnerabilities (KEV) catalog, following reports of active exploitation in the wild. Attackers are already using this issue in real-world attacks, so exposed systems may need both remediation and investigation for earlier compromise.

The significance for defenders depends on whether the organizations, technologies or attack path described in the reporting overlap with their own environment. Inventory the affected product deployments and confirm whether the affected component and vulnerable release are present.
