  - Successful exploitation generates a slow SQL query which causes the
  database engine used by phpBB to consume all available CPU resources.
  Depending upon the database engine, users will also be completely unable
  to create or modify posts due to locks on the search index tables. The
  slowness of the query depends on the size of the search_wordlist and
  search_wordmatch tables (CVE-2019-9826).

  - Server side request forgery (SSRF) allows checking for the existence of files and services on the local
  network of the host through the remote avatar upload function (CVE-2019-11767).");
