Description Martin Prpič 2015-04-28 12:44:44 UTC
A stored cross-site scripting flaw was found in Wordpress:

If the comment text is long enough, it will be truncated when inserted in the database. The MySQL TEXT type size limit is 64 kilobytes so the comment has to be quite long.

The truncation results in malformed HTML generated on the page. The attacker can supply any attributes in the allowed HTML tags, in the same way as the previous stored XSS vulnerabilities affecting WordPress.
