Critical N-able N-central RCE Vulnerability Exploited: MSP Supply Chain Under Attack
In September 2026, CISA added CVE-2026-86218, a maximum-severity remote code execution vulnerability in N-able N-central, to its Known Exploited Vulnerabilities catalog after evidence of active exploitation in the wild. The pre-authentication static code injection flaw allows attackers to execute arbitrary code without authentication on N-central servers, which are widely used by managed service providers (MSPs) and large IT organizations to manage entire customer environments. Huntress reported investigating a compromise of a customer's fully patched N-central production environment, though the exact exploit vector remains unclear. The vulnerability was patched in N-central 2026.3 Hotfix 4, but organizations must also hunt for indicators of compromise as patching alone may be insufficient. This incident highlights the escalating threat to MSP infrastructure as ransomware groups increasingly target supply chain chokepoints to maximize their reach across multiple organizations simultaneously.
