N-able has released a fresh round of hotfixes for N‑central as part of its investigation into ongoing exploitation of a recently disclosed security flaw in the Remote Monitoring and Management (RMM) product.
"We are proactively expanding protections in response to ongoing monitoring of threat actors as they evolve their attack techniques," the company said.
"This is not a duplicate of our previous communication. Hotfix 2 is required, even if you already applied the earlier hotfix. Hotfix 2 supersedes Hotfix 1 with additional hardening measures to further protect you and your customers."
The disclosure comes as N-able acknowledged that it detected unusual activity within a customer's environment on July 31, 2026, leading to the discovery of unknown threat actors exploiting a then-zero-day flaw in the N‑central server (CVE-2026-18577, CVSS score: 8.2). It impacts all versions prior to 2026.3.1.7.
