HighCVSS 7.2Exploitation Probability (EPSS)
Low risk18th percentile - higher than 18% of all known CVEs
Summary
The European VAT Compliance Assistant for WooCommerce plugin is vulnerable to Stored Cross-Site Scripting via the CF-IPCountry header in all versions up to and including 1.36.10 due to insufficient input sanitization and output escaping. Unauthenticated attackers can inject arbitrary web scripts that execute when a user visits the affected page.
Risk Assessment
An attacker can execute arbitrary JavaScript in the user's browser, potentially leading to data or session theft.
Recommendation
Update the plugin to a version later than 1.36.10 that includes sanitization and escaping fixes.

Original NVD description (English source)
The European VAT Compliance Assistant for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via CF-IPCountry Header in all versions up to, and including, 1.36.10 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The malicious header value is persisted verbatim into order post-meta during a guest checkout, meaning no account or authentication is required to plant the payload.
