Enter Addons WordPress Plugin Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the Enter Addons plugin for WordPress, affecting all versions through 2.2.7. The issue arises in the Countdown and Image Comparison widgets, where insufficient input sanitization and output escaping on user-supplied attributes allow authenticated attackers with contributor-level access and above to inject arbitrary web scripts. These scripts execute when a user accesses the compromised page.

Impact

Exploitation of this vulnerability allows for stored cross-site scripting, where injected scripts are executed in the context of the user viewing the page.

Remediation

Users are advised to update the Enter Addons plugin to version 2.2.8 or a newer patched version.
