CVE-2026-18556 is an authentication bypass vulnerability in N-able N-central caused by an alternate path or channel that permits access without successful normal authentication. It affects N-central versions through 2026.1. The flaw enables a remote attacker to bypass the product’s authentication controls and obtain unauthorized access to the N-central management plane. Reporting indicates the issue was actively exploited in the wild and that a later related vulnerability, CVE-2026-18577, resulted from an incomplete remediation of this original flaw.
