Summary
A container privilege escalation flaw was found in certain CodeReady Workspaces images. This issue stems from the /etc/passwd file being created with group-writable permissions during build time. In certain conditions, an attacker who can execute commands within an affected container, even as a non-root user, can leverage their membership in the root group to modify the /etc/passwd file. This could allow the attacker to add a new user with any arbitrary UID, including UID 0, leading to full root privileges within the container.
Risk Assessment
An attacker with command execution in the container can gain root privileges, potentially leading to full control over the container and potentially the host.
Recommendation
Update CodeReady Workspaces images to versions containing the fix. Verify /etc/passwd permissions and restrict command execution in containers.

- CVE-2026-114630Critical
The ELEX WordPress HelpDesk & Customer Ticketing System plugin is vulnerable to arbitrary file deletion due to insufficient file path validation in the factory_reset function in all versions up to, and including, 3.3.8. Unauthenticated attackers can 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). The vulnerability is exploited via a two-step chain: storing an arbitrary ticket_attachment_path value through the public AJAX endpoint, then triggering the factory_reset routine via a GET request.
- CVE-2026-107622Critical
The BuddyForms plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 2.10.5 via a form-type confusion attack through the bf_post_type parameter. Unauthenticated attackers can insert a rogue BuddyForms form configuration with an attacker-controlled new_user_role value into the live global form registry, then submit a registration through that form to create a new WordPress account with administrator-level privileges. Exploitation requires "Anyone can register" enabled and at least one public BuddyForms form attached to a page.

The MDJM Event Management and Mobile Events Manager WordPress plugins through 1.7.8.7 act on a role deletion request on every page load with no capability check and no nonce. The guard meant to protect roles with assigned users reads a different part of the request than the one selecting what is deleted, allowing unauthenticated attackers to remove any WordPress role including administrator, permanently stripping every user of their capabilities.
