Download of code without integrity check vulnerability in N-able N-central allows Remote Code Inclusion. This issue affects N-central: through 24.6.1.
Improper neutralization of input during web page generation ('cross-site scripting') vulnerability in N-able N-central allows Resource Injection. This issue affects N-central: before 26.4.1.
Incorrect privilege assignment vulnerability in N-able N-central allows Privilege Escalation. This issue affects N-central: before 26.4.1.
Server-Side request forgery (SSRF) vulnerability in N-able N-central allows Server Side Request Forgery. This issue affects N-central: before 26.4.1.
Relative path traversal vulnerability in N-able N-central allows Path Traversal. This issue affects N-central: before 26.4.1.
vault token disclosure via unvalidated postMessage vulnerability in N-able PassPortal allows Authentication Abuse. This issue affects the PassPortal browser extension: before 3.49.6.
N-able Mail Assure through April 2026 contains a design-level authorization flaw that allows an authenticated SMTP user to send outbound email using MAIL FROM addresses belonging to other tenants. When connecting to the SMTP TCP port and performing SMTP AUTH with valid credentials, the server accepts arbitrary sender domains without enforcing any domain-to-account binding. As a result, an attacker from any tenant can impersonate other tenant domains, producing messages that pass SPF and DMARC validation. NOTE: N-able's position is that the behavior is intended functionality of its shared SMTP relay architecture and that the service does not represent that it enforces per-tenant sender-domain binding.
N-central is vulnerable to a pre-auth remote code execution This issue affects N-central: before 2026.3.1.14.
An authentication bypass in N-central < 2026.3 HF 3 leads to authentication bypass in internal only APIs
