# CVE-2026-86218: N-able N-central Static Code Injection Vulnerability

**Signal:** Exploited: patch now if you run it. CISA has confirmed exploitation in the wild. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Yes, if you run N-able N-central. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2026-09-08, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2026-09-11 ; treat that as the outer limit, not the target.
- EPSS 13.3% , percentile 96: FIRST’s model estimates a 13.3% chance of exploitation activity in the next 30 days, higher than 96% of all scored CVEs (very high). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Editorial verdict: Act now. N-able N-central: Exploited Auth Bypass and Pre-Auth RCE — Any self-hosted N-central server below 2026.3.1.14 should be treated as exposed and patched today, and any server that was patched late needs a compromise review, because one stolen RMM console reaches every managed endpoint.

## What it is

N-central is vulnerable to a pre-auth remote code execution This issue affects N-central: before 2026.3.1.14.

## Affected products (CVE record)

- N-able N-central: < 2026.3.1.14

## Severity

- N-able CVSS 4.0: 10 `CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H`

## Exploitation

- CISA KEV: added 2026-09-08; federal due date 2026-09-11. Known ransomware use: Unknown.
- CISA required action: Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes). Follow applicable BOD 26-04 guidance for cloud services or discontinue use of the product if mitigations are unavailable. Stakeholders are responsible for evaluating each asset's internet exposure and ensuring adherence to BOD 26-04 patching guidelines.
- CISA SSVC assessment: exploitation active , automatable yes , technical impact total .
- FIRST EPSS (model of 2026-10-21): 13.35% probability of exploitation activity in the next 30 days; percentile 96.
