Name of the Vulnerable Software and Affected Versions Website Optimization – Plerdy plugin for WordPress versions up to, and including, 1.3.2

Description The issue is related to Stored Cross-Site Scripting via the plugin's tracking code settings due to insufficient input sanitization and output escaping. This allows authenticated attackers with administrator-level access to inject arbitrary web scripts in pages, which will execute when a user accesses an injected page. The issue specifically affects multi-site installations and installations where unfiltered html has been disabled.

Recommendations For versions up to, and including, 1.3.2, update to a version that includes the necessary input sanitization and output escaping fixes to prevent Stored Cross-Site Scripting attacks. As a temporary workaround, consider restricting administrator-level access and monitoring page content for injected scripts. Additionally, enabling unfiltered html, if feasible, may mitigate the risk, but this should be carefully considered against potential security trade-offs.
