CVE-2026-2470 — Page Builder: Pagelayer security vulnerability

Medium CVSS 4.3

The Page Builder: Pagelayer – Drag and Drop website builder plugin for WordPress is vulnerable to Incorrect Authorization in all versions up to, and including, 2.0.9. This is due to the pagelayer_save_content AJAX handler allowing users with basic post-edit capability to persist pagelayer_contact_templates metadata on posts they can edit (including pending posts), while the unauthenticated pagelayer_contact_submit endpoint later consumes that metadata by user-controlled post/form identifiers without enforcing a privileged or published-context boundary. This makes it possible for authenticated attackers, with Contributor-level access and above, to configure arbitrary contact-form mail templates that are usable through unauthenticated form submission via the contacts parameter. In typical deployments this template feature is configured via Pagelayer Pro UI; however, the vulnerable backend trust path is still present. This issue may be chained with CVE-2026-2442 to increase exploitability and attacker control over outbound email behavior.

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.
