Uncanny Automator WordPress Plugin Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the Uncanny Automator WordPress plugin, specifically in versions through 6.10.0.2. The issue arises in the automator_discord_user_mapping shortcode, where inadequate input sanitization and output escaping of the verified_message parameter allow authenticated attackers with Contributor-level access or higher to inject arbitrary web scripts. These scripts execute when a user with a verified Discord account accesses the affected 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 Uncanny Automator WordPress plugin to version 7.0.0 or later.
