CVE intelligence and bounded remediation

CVE-2025-0515 — Buzz Club – Night Club, DJ and Music Festival Event WordPress Theme the… security vulnerability

Medium CVSS 4.3

The Buzz Club – Night Club, DJ and Music Festival Event WordPress Theme theme for WordPress is vulnerable to unauthorized modification of data that can lead to a denial of service due to a missing capability check on the 'cmsmasters_hide_admin_notice' function in all versions up to, and including, 2.0.4. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update option values to 'hide' on the WordPress site. This can be leveraged to update an option that would create an error on the site and deny service to legitimate users or be used to set some values to true such as registration.

Matched remediation archetype

Authorization bypass, IDOR, and cross-tenant access

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
  • Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
  • Use synthetic fixtures to compare intended access matrices without accessing another user's real data.

Remediate safely

  • Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
  • Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
  • Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
