CVE-2025-8876Known exploitationNetwork attack vector

Authenticated command execution via improperly validated input

Published Aug 14, 2025 · Updated Oct 21, 2025

OS command injection in N-able N-central before 2025.3.1 allows remote authenticated users to execute commands through crafted input. N-able attributes the flaw to improper input validation but has not disclosed the affected endpoint, parameter, or command-construction path. Low-privileged authentication is required, and successful exploitation grants command execution in the N-central environment.
