Medium CVSS 4.3

The User Shortcodes Plus plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 2.0.2 via the user_meta shortcode due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with contributor-level access and above, to retrieve potentially sensitive user meta.

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.
