High risk81th percentile - higher than 81% of all known CVEs
Summary
A security vulnerability was detected in WAVLINK WL-WN579A3-A (version 2026-03-10-94f93d4) in the set_wzdgwMesh function of /cgi-bin/adm.cgi, within the Initial Setup Wizard component. Manipulation of the wlan_ssid argument leads to OS command injection. The attack can be carried out remotely and the exploit has been publicly disclosed.
Risk Assessment
A remote attacker could execute arbitrary commands on the device, potentially leading to compromise of the router and the network. The public disclosure of the exploit increases the risk of exploitation.
Recommendation
Update the device firmware to the vendor-patched version as soon as possible or restrict access to the management interface. Until a fix is available, disable remote access to the administrative panel.

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.
