CVE-2023-1259 Information

Description

The Hotjar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the hotjar_site_id in versions up to and including 1.0.15 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.
