## What to check

- Applies to: The 7 CVEs named below. Whether you run an affected version is not assessed: check the versions the source lists.
- Exploitation: No exploitation in the wild and no public exploit is recorded for the CVEs named.

NCSC-NL published an advisory detailing multiple vulnerabilities patched in N-able N-central, a remote monitoring and management (RMM) platform widely used by managed service providers. The flaws span several vulnerability classes: XML External Entity (XXE) injection affecting XML data processing, OGNL injection and stored Cross-Site Scripting (XSS) that can execute malicious code in the web interface including in an administrator context, local privilege escalation via insecure syslog-ng configuration and unsafe inter-process communication (IPC) channels, Server-Side Request Forgery (SSRF) via schema validation during service import, and a path traversal issue in file repository uploads that can lead to Remote Code Execution (RCE).

All issues affect versions prior to 2026.4.1.26. N-able has released N-central 2026.4 HF2 (build 2026.4.1.26) to remediate the vulnerabilities. CVSS v4 scores range from 8.3 to 9.3, with the path-traversal-to-RCE issue (CVE-2026-125883) and another flaw (CVE-2026-125881) both scoring 9.3. No in-the-wild exploitation is mentioned in the advisory.

Defenders running N-able N-central should prioritize upgrading to build 2026.4.1.26 or later given the RMM platform's privileged position in managed-service environments; successful exploitation chaining the RCE, privilege escalation, and SSRF issues could grant an attacker significant control over the management server and downstream managed endpoints.
