The WP-Syntax plugin for WordPress is vulnerable to Regex Denial of Service in all versions up to, and including, 1.2. This is due to plugin not properly validating a regex before running it. This makes it possible for authenticated attackers, with Author-level access and above, to cause a limited denial of service based on a faulty regex.
