The Wordfence3 Intelligence team recently identified an open redirect vulnerability in Bridge, a commercial WordPress theme purchased more than 120,000 times. We disclosed this issue to Qode Interactive, the theme’s developers, who have since released a patch for the affected components.

The initial discovery was related to one of the theme’s prepackaged helper plugins, Qode Instagram Widget. After discovery, Qode’s team patched a similar open redirect flaw in another prepackaged plugin, Qode Twitter Feed. Both of these plugins should be updated to their latest version, which is 2.0.2 in both cases at the time of this writing. These updates will be accessible from within the Bridge theme’s recommended plugin manager once the theme has been updated to 18.2.1.

We have released new firewall rules which protects Wordfence users’ sites from abuse of these open redirects. Wordfence Premium users already have access to these rules, and users still on the free version will have access in thirty days.

In today’s post, we’ll take a look at the vulnerabilities that were patched, and we’ll briefly discuss the risk that an open redirect vulnerability presents. Update workflows can vary for commercial themes and plugins such as these, so we’ll additionally be providing a short guide to help Bridge users ensure they’re up to date.

What Is An Open Redirect?

An open redirect vulnerability exists when a web application can be made to redirect a visitor to an arbitrary location based on user input. This can be used to create innocent-looking web links to legitimate domains, which then redirect the victim to a dangerous location. This is commonly used in phishing scams, since a link to a trustworthy site is much more likely to be clicked than a typical phishing domain.

How Do I Patch?

Commercial WordPress themes and plugins often have update workflows that differ from those native to the WordPress.org repository. In the case of the Bridge theme and its associated plugins, it seems many users aren’t getting the updates they need. According to our data, 38% of active Qode Instagram Widget installations haven’t been updated in more than two years, and that number jumps to 68% for Qode Twitter Feed users.

Updating these plugins first requires users to update the Bridge theme. This is done either by manually downloading and installing an updated copy of the theme from ThemeForest, or by using the Envato Market plugin which also comes bundled with the Bridge theme to update from within the WordPress dashboard.

It is important that you update and patch this theme if you are using it.
