This is a warning that a Reflected Cross-Site Scripting (XSS) vulnerability has been discovered in versions 2.4.0 or lower of the GP Premium plugin. If you have received this email, you must update GP Premium to the latest version to securely operate your site. If you have already updated, you can disregard this message. (Cloudways sends notification emails when it detects WordPress cores, themes, or plugins that have not been properly updated and still contain security vulnerabilities.

You can check the update history on the GeneratePress Changelog page. It describes the GP Premium 2.4.1 as a security release addressing a potential XSS vulnerability, marked in the changelog as "Security: Harden variable against XSS attacks." No specific details are provided.

How to Update GP Premium

GP Premium is a paid plugin that requires a license to update. If your license key is registered, you can automatically update it by clicking the update button on the WordPress dashboard.

Update failed: Download failed. Unauthorized Error

If you encounter the error "Update failed: Download failed. Unauthorized" during the update attempt, it means that the license key is incorrect.

Navigate to Appearance » GeneratePress » License Key section and click the "Clear key" button to deactivate the license key.

Re-enter the license key and register it again, and the update should proceed normally.

Manually Updating the Plugin

If the update still fails, you can manually update by downloading the latest version of the plugin file from the GP site and uploading it.

You can download the GP Premium installation file from the GeneratePress site, and then upload the file by clicking on Plugins » Add New Plugin » Upload Plugin.

Insufficient Server Disk Space

If it still fails, check if there is enough disk space on your web server. Many installation or update failures for WordPress themes/plugins occur due to insufficient disk space. Local hosting services like Cafe24 often have small disk capacities, so using a low-priced product can quickly exhaust the allocated web server capacity.

If you are running low on disk space, you might consider hosting services like FastComet, which offers affordable web hosting products, or Cloudways, known for its fast speeds and user-friendly interface.

The Importance of Updates

To safely operate your WordPress site, it is crucial to keep the WordPress core, themes, and plugins up-to-date. Especially when security vulnerabilities are discovered and updated in popular themes or plugins installed on many sites, it is vital to update to the latest version to ensure safety.

Failing to update after a security patch has been implemented can result in malware infections. Once vulnerabilities in popular themes or plugins are publicized, malicious attackers can create and distribute malware that exploits these vulnerabilities.

In fact, neglecting updates has led to many sites being infected. Last September and October, some sites were infected with malware because they did not update the popular news, magazine, and blog theme, Newspaper. Cases of malware infection have been observed recently in sites that have not updated the Newspaper theme.

Final Thoughts

Since GP Premium is installed on many sites, it is expected that attacks exploiting this vulnerability will appear soon.

It is helpful to regularly backup data and databases to a PC or cloud storage in preparation for any incidents. Treating malware infections is not easy, and even if the infected files are removed, they can recur if security measures are not properly implemented. Thus, prevention is the best approach.
