Summary
The Payment Plugins for Stripe WooCommerce plugin for WordPress is affected in all versions up to and including 4.0.17. Insufficient input sanitization and output escaping (CWE-79) let an unauthenticated attacker inject scripts through the '#response' URL fragment, and they run whenever a user opens an injected page. Exploitation requires the 'Generic Errors' setting to be unchecked, which makes the raw Stripe error string appear unchanged.

Description from the CNA
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.
