In versions prior to 11.3.3, the `MessagesController` class of OpenProject has a `quote` method that implements the logic behind the Quote button in the discussion forums, and it uses a regex to strip `&lt;pre&gt;` tags from the message being quoted. The `(.|\s)` part can match a space character in two ways, so an unterminated `&lt;pre&gt;` tag containing `n` spaces causes Ruby&#39;s regex engine to backtrack to try 2&lt;sup&gt;n&lt;/sup&gt; states in the NFA. This will result in a Regular Expression Denial of Service. The issue is fixed in OpenProject 11.3.3. As a workaround, one may install the patch manually.</p> <p><strong>Affected:</strong> opf openproject</p> <p>OpenProject is open-source, web-based project management software.
