Description

The Payment Plugins for Stripe WooCommerce plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via '#response' URL Fragment in all versions up to, and including, 4.0.17 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. Exploitation requires that the 'Generic Errors' setting is unchecked, causing getErrorMessage() to return the raw Stripe error string unchanged rather than substituting a mapped safe message.
