CVE-2026-83805
Nautobot is a Network Source of Truth and Network Automation Platform. From 3.0.0 until 3.1.8, the generic ApprovalWorkflowStageResponse create endpoint does not enforce approver-group membership, change permission on the object under review, or the one-response-per-user restriction applied by the intended approve and deny actions. A user with only extras.add_approvalworkflowstageresponse can submit approved responses directly, while writable user and state fields permit responses to be attributed to arbitrary users. These forged responses can satisfy min_approvers, approve the workflow, and activate its gated ScheduledJob without a legitimate approver. This issue is fixed in version 3.1.8.

CVE-2026-83801
Nautobot is a Network Source of Truth and Network Automation Platform. Prior to 2.4.37 and 3.1.8, a user with extras.add_relationship or extras.change_relationship permission can store HTML or JavaScript in a Relationship description, and a user with dcim.add_modulefamily or dcim.change_modulefamily permission can store it in a Module Family name. Nautobot assigns these values to form field help_text rendered by render_field.html through Django's |safe filter without adequate neutralization. The stored content executes in the authenticated browser session of any user, including an administrator or superuser, who opens an affected create or edit form. This can enable actions as the victim, session or token theft, and further privilege escalation. This issue is fixed in versions 2.4.37 and 3.1.8.

CVE-2026-79767
Gardener implements the automated management and operation of Kubernetes clusters as a service. Prior to 1.142.6, 1.143.3, 1.144.2, and 1.145.0, the customverbauthorizer admission plugin's mustCheckProjectMembers manage-members check compares changes to User subjects but does not account for Group or ServiceAccount subjects in Project.spec.members. A project administrator who lacks manage-members permission can add arbitrary Group or ServiceAccount subjects, including the system:authenticated Group, and thereby grant broad project access. The resulting access can include Shoots, Secrets, and cloud provider credentials. This issue is fixed in versions 1.142.6, 1.143.3, 1.144.2, and 1.145.0.
