Minify HTML < 2.1.11 - - Regular Expressions Denial of Service

Description

The Minify HTML plugin for WordPress is vulnerable to Regular Expression Denial of Service (ReDoS) in all versions up to, and including, 2.1.10. This is due to processing user-supplied input as a regular expression. This makes it possible for unauthenticated attackers to create comments that can cause catastrophic backtracking and break pages.
