Technical description

NordVPN for Windows allows local attackers to stop unprotected Windows system services and change their startup type to Manual via named pipes. The NordVPN user-mode application allows a low-privileged attacker to act as a trusted process and connect to the named pipe "\\.\pipe\nord-security\v1\NordVpnService\Server". The attacker can then invoke the "ISettingsGrpc.StopService" and "ISettingsGrpc.ChangeServiceStartType" methods with an arbitrary service name, allowing them to stop any unprotected Windows service and change its startup type. This leads to denial of service of critical system services. Services protected by Windows (PPL processes, Windows Tamper Protection), such as Windows Defender, cannot be stopped or reconfigured. This issue was fixed in version 8.12

———The WSP MCP AI Agents Connector plugin for WordPress is vulnerable to Sensitive Information Disclosure in versions up to, and including, 2.9.5. This is due to the wsp_get_posts MCP tool being registered with an empty capability requirement while the MCP endpoint's authenticate() method accepts any logged-in user, and the wsp_execute_get_posts() callback honouring a caller-supplied status=all argument that expands into a WP_Query over 'publish', 'draft', 'pending' and 'future' posts with no author or ownership filter. This makes it possible for authenticated attackers, with Subscriber-level access and above, to read the titles, URLs, authors, categories, tags and 40-word excerpts of every unpublished (draft/pending/scheduled) post on the site.9h CVE-2026-1114468.6 HIG

———Wheels 4.0.0 through 4.1.2 exposes password-less development tools under /wheels/* to remote clients when enablePublicComponent=true, as it is by default in development. Before 4.1.2 these tools have no local-access restriction; in 4.1.2 the restriction trusts client-supplied headers without checking the connecting peer. Remote clients can obtain application settings, environment/datasource details and routes, and start test runs. Where application tests use the primary datasource, those runs can write to the real application database. The separately protected migrator and CLI endpoints are not affected. This is fixed in 4.2.0.12h
