Technical description

The Subscriptions for WooCommerce plugin for WordPress is vulnerable to Privilege Escalation in versions up to, and including, 2.0.0. This is due to the `save_meta_boxes()` function persisting the `_wps_plan_user_role` membership plan meta from `$_POST` without an allowlist that excludes privileged roles — the only validations applied, `sanitize_key()` and `wp_roles()->is_role()`, both accept `'administrator'` as a valid value, and the UI's `disabled` attribute on the role dropdown is a client-side-only control trivially bypassed via DevTools or a direct POST request; additionally, because the `wps_membership_plan` custom post type is registered with `capability_type => 'post'`, any user who can edit posts satisfies the `current_user_can('edit_post', $post_id)` guard in `save_meta_boxes()`. This makes it possible for authenticated attackers, with Contributor-level access and above, to escalate their privileges to Administrator by storing `'administrator'` as the role granted on membership acquisition, which the Pro companion plugin then applies via `add_role()` during membership lifecycle events. Successful exploitation requires the Subscriptions for WooCommerce Pro companion plugin to be active, as it is the component that reads the stored `_wps_plan_user_role` meta via `get_post_meta()` and calls `add_role()` to apply the role during membership lifecycle events.

CVE-2026-166358.8 HIG

—

——0The Pronamic Pay plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 10.1.0 This is due to the `maybe_update_user_role()` function passing an attacker-controlled Gravity Forms field value (`$lead[$feed->user_role_field_id]`) directly into `WP_User::set_role()` without any allowlist validation, capability comparison, or permission check to constrain which roles can be assigned. This makes it possible for authenticated attackers, with Subscriber-level access and above, to escalate their own WordPress account to Administrator by tampering with the role field value in a form submission. Exploitation requires that an administrator has already configured a Pronamic Pay payment feed in Gravity Forms with the **Update User Role** option enabled and mapped to a form field; once that configuration is in place, no further preconditions exist to prevent an authenticated attacker from exploiting this vulnerability.1d CVE-2026-143337.5 HIG

——1The Demi WordPress plugin before 0.0.7 stores its full-site backup archives in a publicly accessible location under a predictable filename and without access protection, allowing unauthenticated attackers to download complete backups including the site database and its user password hashes.2d CVE-2026-122518.1 HIG

——1The Ultimate Member WordPress plugin before 2.12.1 does not filter administrator-level capabilities from the roles it makes selectable on its registration forms, and its post-registration safeguard against elevated accounts is disabled by default, allowing unauthenticated users to register with a site-defined role that carries administrator capabilities and gain administrative access, when such a role exists and a role-selection field is present on a published registration form.2d CVE-2026-658356.6 MED

——3Capsule is a multi-tenancy and policy-based framework for Kubernetes. From 0.13.0 until 0.13.8, after the incomplete CVE-2026-22872 fix, TenantResource RawItems and Generators in internal/controllers/resources/collect.go, including handleRawItem and handleGeneratorItem, did not apply the ResourceReference.LoadResources and IsNamespacedGVK cluster-scoped resource rejection guard used by NamespacedItems, allowing a Tenant Owner to create cluster-scoped resources such as ClusterRole or ValidatingWebhookConfiguration through the cluster-admin controller client.

——7The ProfileGrid WordPress plugin before 5.9.9.8 does not restrict which group an anonymous visitor may register into through its front-end registration, allowing unauthenticated users to register directly into a privileged group and be granted that group's configured role, up to Administrator when such a group exists, leading to privilege escalation.3d
