Medium CVSS 5.4

The Elementor Header & Footer Builder for WordPress is vulnerable to HTML Injection in all versions up to, and including, 1.6.26 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with author-level permissions and above, to inject arbitrary HTML in pages that will be shown whenever a user accesses an injected page.

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.
