Assigner: Wordfence

Description
The GPXpress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'gpxpress' shortcode in all versions up to, and including, 1.3 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Can you explain this vulnerability to me?

This vulnerability is a Stored Cross-Site Scripting (XSS) issue in the GPXpress plugin for WordPress, affecting all versions up to and including 1.3. It occurs because the plugin does not properly sanitize or escape user-supplied attributes in its 'gpxpress' shortcode. Authenticated users with contributor-level access or higher can inject malicious scripts that will execute whenever any user views the affected page.


How can this vulnerability impact me? :

The vulnerability allows attackers with contributor-level access or higher to inject arbitrary scripts into pages, which can lead to unauthorized actions such as stealing user credentials, hijacking user sessions, defacing websites, or distributing malware to visitors. This compromises the integrity and security of the affected WordPress site and its users.


What immediate steps should I take to mitigate this vulnerability?

To mitigate this vulnerability, immediately update the GPXpress plugin for WordPress to a version later than 1.3 where the issue is fixed. Additionally, restrict contributor-level access and above to trusted users only, and consider reviewing and sanitizing any user-supplied content in the 'gpxpress' shortcode attributes to prevent stored cross-site scripting attacks.
