CVE-2026-18577 is an authentication bypass vulnerability in N-able N-central caused by an incomplete remediation of CVE-2026-18556. The flaw affects N-central server deployments and allows a remote, unauthenticated attacker to bypass normal login controls and take over an administrator account or otherwise obtain full administrative access to the N-central management plane. Reporting indicates the issue was actively exploited as a zero-day and that attackers were able to abuse the resulting privileged access to operate the platform as a trusted administrator. Because N-central is a remote monitoring and management platform, compromise of the server can expose the broader managed environment. Some reporting indicates the initial fix was delivered in 2026.3.1.7 and later supplemented by additional hardening in 2026.3.1.10 due to continued exploitation.
