CVE-2024-0903: userfeedback vulnerability

What is known

The User Feedback – Create Interactive Feedback Form, User Surveys, and Polls in Seconds plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'page_submitted' 'link' value in all versions up to, and including, 1.0.13 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in the feedback submission page that will execute when a user clicks the link, while also pressing the command key.

Business impact

Successful exploitation of CVE-2024-0903, a medium vulnerability (CVSS 5.4) affecting userfeedback, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.

Recommended administrator action

Confirm whether userfeedback is present and compare installed versions with the vendor advisory and NVD record. Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation. DataHouse can support version verification, managed patching, network exposure reduction, log review and backup validation for dedicated, cloud and colocated environments.
