description
EU VAT Assistant for WooCommerce versions through 2.1.30.260413 are affected by stored cross-site scripting. An unauthenticated attacker may cause content to execute in an administrator’s browser when that administrator reviews an affected order, potentially allowing actions with administrative privileges.
mitigation
Disable the affected plugin or restrict untrusted users from submitting VAT numbers until the vendor provides and you can deploy a corrected release. Review recent orders for suspicious VAT-number content and avoid opening untrusted order records in an administrator session.
outcome
Contextual: an exploit technique exists, but no deterministic check could cover this one.
