WP Delete Post Copies Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the WP Delete Post Copies plugin for WordPress, affecting all versions through 6.0.2. This vulnerability arises from inadequate input sanitization and output escaping, allowing authenticated attackers with administrator-level permissions to inject arbitrary scripts. The injected scripts execute when users access the compromised pages. This issue is present in multi-site installations where unfiltered HTML is disabled.

Impact

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

Remediation

Users can update to WP Delete Post Copies version 6.0.3 or a newer patched version to address this vulnerability.
