The Newsletter WordPress plugin before 9.3.7 does not validate the destination of the redirect performed after a public subscription action, allowing unauthenticated attackers to redirect users to arbitrary external sites and to disclose a subscriber token that grants access to that subscriber record's front-end actions.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
| Vendor | Product | Default status | Versions | ||||||
