AI-GeneratedThe Highlighting Code Block plugin for WordPress is vulnerable to Stored Cross-Site Scripting due to inadequate input sanitization and output escaping, affecting all versions up to 2.2.0. Authenticated attackers with administrator-level permissions can exploit this vulnerability to inject malicious scripts that execute when users access compromised pages, particularly in multi-site installations or where unfiltered_html is disabled. WordPress site administrators, especially those managing multi-site setups, should prioritize addressing this vulnerability to mitigate potential security risks.
Original NVD Description
The Highlighting Code Block plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 2.2.0 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.
