What it is
Access to a resource or action is not restricted to the people meant to have it.
How it is reached
An attacker can exploit it over the network, without an account, and nobody has to click anything.
What an attacker gains
The direct impact is limited: partial access to data or a partial outage. In practice, this kind of flaw lets an attacker reach data or actions their role should not allow.
Is it being exploited?
There is no public report of exploitation yet. It can be exploited automatically, at scale. EPSS estimates a 0.19% chance of exploitation activity in the next 30 days, higher than 9% of scored CVEs.
What to do
- Upgrade Subscriptions for WooCommerce to 2.1.1 or later.
- Until it is patched, keep it off the internet or behind a VPN, allowlist or authenticating proxy.
Description from NVD
The Subscriptions for WooCommerce WordPress plugin before 2.1.1 only enforces its membership content restrictions on standard front-end page views, allowing unauthenticated users to read the full contents of restricted posts and pages through other routes that render the same content.
What this means for your architecture.
A CVE names a product. Whether it matters depends on where that product sits in your systems: what reaches it, which trust boundary it guards and what it can reach once compromised. Veriom maps your components, their relationships and your trust boundaries from your code, cloud and delivery evidence, so you can see where a component like this sits. The radar itself does not look at your systems.
Components it touches
- WordPress sites and their plugins. Plugins run inside the site with its database access, and many sites are public.
- Permission checks in APIs and admin surfaces. The flaw sits between one role or tenant and another.
- Multi-tenant services. The flaw sits between one role or tenant and another.
Trust boundaries in play
- Internet-facing entry points. No account is needed. Any instance reachable from outside your perimeter, through a load balancer, gateway, VPN or exposed admin port, is in scope.
- Between one role or tenant and another. An attacker who crosses it can reach data or actions their role should not allow.
Questions to answer about your own systems
- Where does Subscriptions for WooCommerce run in your systems, and at which version?
- Which of those instances can be reached from the internet or partner networks?
