Users should monitor the vendor's advisory for updates. Until a fix is available, restrict administrator access to trusted users only and consider disabling or removing the Simple Share Buttons Adder plugin in multi-site or unfiltered_html-disabled environments to mitigate risk.
Description
The Simple Share Buttons Adder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 8.4.11 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
