The auto-completion plugin in Ametys CMS before 4.5.0 allows a remote unauthenticated attacker to read documents such as plugins/web/service/search/auto-completion//en.xml (and similar pathnames for other languages), which contain all characters typed by all users, including the content of private pages. For example, a private page may contain usernames, e-mail addresses, and possibly passwords.

  • →HTTP GET request to the auto-completion XML path with any query parameter (e.g. ?q=adm) returns HTTP 200 with Content-Type: text/xml and XML tags <words> and <word> in the body, indicating unauthenticated information disclosure. ↗
  • →The vulnerability is exploitable by a remote unauthenticated attacker (no authentication required, network-accessible), targeting Ametys CMS versions before 4.5.0 via the auto-completion plugin endpoint. ↗
  • ·The vulnerable path uses 'domain' as a placeholder — the actual segment may vary per deployment. Similar pathnames exist for other languages beyond 'en.xml' (e.g., fr.xml, de.xml), so detection rules should account for wildcard language codes. ↗
