AI analysisSummaries by Vani AI
N-able N-central before 26.4.1 does not neutralize scripting syntax in HTTP headers, allowing cross-site scripting. A high-privileged attacker on the network can send a crafted request; a user must actively interact for the script to run. That can expose or change data in the victim's session, with limited availability impact. Unpatched N-central deployments are affected.
What to do: Upgrade N-able N-central to 26.4.1.
| Product | Affected | Fixed in |
