In Drupal's 3rd party module search auto complete prior to versions 7.x-4.8 there is a Cross Site Scripting vulnerability. This Search Autocomplete module enables you to autocomplete textfield using data from your website (nodes, comments, etc.). The module doesn't sufficiently filter user-entered text among the autocompletion items leading to a Cross Site Scripting (XSS) vulnerability.

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.
