CVE-2026-15285 — Plus Addons for Elementor security vulnerability

Medium CVSS 6.4

The Plus Addons for Elementor plugin for WordPress was vulnerable to Authenticated (Contributor+) Stored Cross-Site Scripting via the Button widget's `custom_attributes` setting in versions up to and including 6.4.11. The `render` function in `modules/widgets/tp_button.php` passed the raw `custom_attributes` string through `tp_senitize_js_input()`. This filter is bypassable. The issue is patched in version 6.4.12.

Matched remediation archetype

Cross-site scripting and unsafe browser output

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

Check exposure

  • Trace reflected, stored, and DOM-derived untrusted values into HTML, attributes, URLs, styles, scripts, and client-side template sinks.
  • Identify affected origins, authenticated user roles, sensitive browser capabilities, and where content is shared across tenants.
  • Review framework escaping, rich-text sanitization, legacy templates, and client-side rendering paths.

Remediate safely

  • Use context-aware framework output encoding and safe DOM APIs; keep untrusted data out of executable contexts.
  • Sanitize intentionally supported markup with a maintained allowlist policy and validate URLs and attributes separately.
  • Update affected rendering components and add tests for every output context using inert sentinel markup.
