Description
The wpLingua plugin for WordPress is vulnerable to Denial of Service via comment content in all versions up to, and including, 3.1.1. This is due to the bundled HTML DOM parser's restore_noise() function replacing an unknown '___noise___' placeholder with text that contains the same token again, so its loop never ends. This makes it possible for unauthenticated attackers to post text containing a forged placeholder that makes every request for the translated version of the affected page loop until it hits the PHP execution time or memory limit, so those translated pages stop rendering.
