CVE-2026-58930
UnknownSummary
An unprivileged application can exploit a lack of package/signature validation in SystemUI's RemoteQCController when resolving a hardcoded content:// URI. This allows the attacker to squat on a specific authority if the legitimate package is absent, inject spoofed UI elements into the trusted SystemUI Quick Controls panel, and gain a Background Activity Launch (BAL) grant from SystemUI when the user interacts with the spoofed element.
Risk Assessment
An attacker could inject spoofed UI elements into the trusted SystemUI panel and gain background activity launch privileges. This may lead to actions in the context of a trusted system component.
Recommendation
Update SystemUI to a version that validates package and signature in RemoteQCController. Ensure content:// URI resolution verifies package identity.

- CVE-2026-102435Critical
The Ultra Addons for Contact Form 7 plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the _getObjAttr function in all versions up to, and including, 3.5.54. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). This requires the PDF Generator add-on to be active and a Contact Form 7 form to be configured for PDF generation.

- CVE-2026-94290Critical
The SUSE Rancher Fleet controller did not sufficiently restrict which kubeconfig secrets a Fleet Cluster object was allowed to reference. As a result, an ordinary user could define a cluster in a namespace they control and associate it with administrative credentials for the management cluster, causing the controller to manage the management cluster on that user's behalf with elevated privileges. This affects Fleet 0.16.0–0.16.3, 0.15.0–0.15.8, 0.14.0–0.14.12, 0.13.0–0.13.17 and possibly older versions.
Original NVD description (English source)
An unprivileged application can exploit a lack of package/signature validation in SystemUI's `RemoteQCController` when resolving a hardcoded `content://` URI. This allows the attacker to squat on a specific authority if the legitimate package is absent, inject spoofed UI elements into the trusted SystemUI Quick Controls panel, and gain a Background Activity Launch (BAL) grant from SystemUI when the user interacts with the spoofed element.
