CNA source text (English)
Simple Membership < 4.7.5 - Unauthenticated Stored XSS via Stripe Webhook API Version
The Simple Membership WordPress plugin before 4.7.5 does not verify the authenticity of Stripe webhook requests when no signing secret is configured, nor escape a value taken from them before outputting it in an administrator notice, allowing unauthenticated attackers to inject arbitrary web scripts that execute in the context of a logged-in administrator.
