Technical description

A privilege escalation vulnerability in Authentik Security authentik through 2026.5.6 allows an attacker with a source-scoped SCIM provisioning token to take over any user account including superusers by provisioning a SCIM user that matches an existing local user by username. The SCIM user ingest function adopts pre-existing local accounts by username without validating scope boundaries. An attacker can rewrite or delete any account, including the superuser, using only a limited provisioning credential.

———Improper privilege management for some Intel(R) PROSet/Wireless WiFi Software for Windows within Ring 2: Privileged Process may allow an escalation of privilege. Unprivileged software adversary with an unauthenticated user combined with a high complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (low), integrity (low) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (low), integrity (low) and availability (high) impacts.5h CVE-2026-725348.8 HIG

———A privilege escalation vulnerability in Authentik Security authentik through 2026.5.6 allows an attacker with a source-scoped SCIM provisioning token to gain superuser privileges by provisioning a SCIM group that matches an existing administrator group by name. The SCIM group ingest function adopts any existing group by name and replaces its membership without validating the source scope against the target group. An attacker can grant their provisioning token full IdP superuser access and lock out all existing administrators.6h CVE-2026-728869.9 CRI

——0Dokploy is a free, self-hostable Platform as a Service (PaaS). From 0.29.2 until 0.29.13, schedule.create and schedule.update in apps/dokploy/server/api/routers/schedule.ts derive serviceId from applicationId or composeId and execute the owner/admin host-schedule gate only in the alternative branch, allowing a member with access to one application to attach its applicationId to a dokploy-server schedule and run a supplied script as root through schedule.runManually. This issue is fixed in version 0.29.13.1d CVE-2026-728639.9 CRI

——0Dokploy is a free, self-hostable Platform as a Service (PaaS). Prior to 0.29.13, Dokploy's WebSocket handlers (in-app terminals and log streamers) authenticate the session but never authorize it. They establish who the user is via validateRequest() and then proceed without consulting the role/permission model that every tRPC procedure enforces. Any authenticated member, can therefore open an interactive shell into any container on the host, including the dokploy container that mounts the Docker socket, and from there obtain root on the host, escaping the application and crossing every tenant boundary. This vulnerability is fixed in 0.29.13.1d CVE-2026-167426.7 MED
