CVE-2026-1925: EmailKit – Email Customizer for WooCommerce & WP <= 1.6.2 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Post Title Modification

The EmailKit – Email Customizer for WooCommerce & WP plugin for WordPress is vulnerable to unauthorized data modification due to a missing capability check on the 'update_template_data' function in all versions up to, and including, 1.6.2. This makes it possible for authenticated attackers, with Subscriber-level access and above, to modify the title of any post on the site, including posts, pages, and custom post types.

Security readout for executives and security teams

Plain-English summary

CVE-2026-1925 affects the EmailKit WordPress plugin. A logged-in low-privilege user can change the title of any post, page, or custom post type. This is not a site takeover, but it can deface content, disrupt storefront communications, and damage trust on affected WordPress sites.

Executive priority

Prioritize remediation for public WordPress or WooCommerce sites with user registration enabled. The issue is moderate severity because it requires login and affects integrity only, but visible content tampering can create business, brand, and customer trust impact.

Technical view

The issue is CWE-862: missing authorization in EmailKit’s update_template_data function. Sources state all versions up to and including 1.6.2 allow authenticated Subscriber-level users or higher to modify arbitrary post titles. CVSS 3.1 is 4.3: network-accessible, low complexity, low privileges, no user interaction, integrity impact only.

Likely exposure

Exposure is limited to WordPress sites running EmailKit – Email Customizer for WooCommerce & WP version 1.6.2 or earlier where untrusted users can authenticate. Sites without this plugin, without affected versions, or without low-privilege user accounts are less likely exposed.

Exploitation context

The provided sources do not show active exploitation, and the CVE is not listed as CISA KEV in the bundle. Abuse requires an authenticated account at Subscriber level or higher. The impact is unauthorized title modification, not code execution or data theft based on available evidence.

Researcher notes

The source bundle identifies affected versions through 1.6.2 and references WordPress Trac code and a changeset, but does not clearly name a fixed release. Validate remediation against vendor or WordPress plugin guidance before closing findings.

Mitigation direction

  • Inventory WordPress sites for the EmailKit plugin and installed version.
  • Treat EmailKit versions 1.6.2 and earlier as affected.
  • Check WordPress plugin and vendor guidance for the fixed release.
  • Update the plugin when a fixed version is confirmed available.
  • Restrict or review low-privilege accounts on affected sites until remediated.

Validation and detection

  • Confirm whether EmailKit is installed on each WordPress site.
  • Check whether the installed version is 1.6.2 or earlier.
  • Review the update_template_data handler for an authorization capability check.
  • Audit recent post, page, and custom post type title changes.
  • Review low-privilege user activity for unexpected content edits.
