The Custom Block Builder WordPress plugin before 3.0.0 does not properly deny unauthorised requests to its REST routes, as its permission checks return a non-error response that WordPress treats as granted, allowing unauthenticated users to execute arbitrary PHP code on the server.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
| Vendor | Product | Default status | Versions | ||||||
