Stored Cross-Site Scripting Vulnerability Affects Add Widget After Content Plugin

CVE-2024-9892

Summary

The Add Widget After Content plugin for WordPress has a vulnerability that allows for Stored Cross-Site Scripting due to inadequate input sanitization and output escaping in its admin settings.

It's important to note that this vulnerability affects only multi-site installations and setups where unfiltered_html has been disabled.
