CVE-2025-8876 is an OS command injection vulnerability in N-able N-central caused by improper input validation and improper sanitization of user-supplied input. The flaw affects N-central versions prior to 2025.3.1 and allows an authenticated attacker to inject and execute arbitrary operating system commands on the underlying N-central server. Public reporting also characterizes the issue as a post-authentication command injection vulnerability affecting on-premises deployments, with active exploitation observed in the wild at the time of disclosure.
