Descripción técnica

The Simple Membership plugin for WordPress is vulnerable to unauthorized modification of data and sensitive information disclosure in versions up to, and including, 4.8.3 via the resend-activation and email-activation endpoints. The endpoints are dispatched from SwpmInitTimeTasks::check_and_do_email_activation() on frontend init with no authentication, nonce, capability, or ownership check, and the recipient address used by SwpmRegistration::send_reg_email() is taken from an attacker-controlled $_POST['email'] parameter (overriding the member's registered address). This makes it possible for unauthenticated attackers to redirect an arbitrary pending member's activation email — and the follow-up 'registration complete' email containing the member's username and plaintext password — to an attacker-chosen address, and to then activate that member's account without their consent.

———A flaw was found in the Dynamic Client Registration flow of the Keycloak identity and access management server. The issue occurs because the registration process fails to filter security-sensitive client attributes when a new client is created. An attacker with a valid Initial Access Token can register a client that bypasses audience checks during token introspection. This allows the attacker to view sensitive identity information, roles, and session details from access tokens belonging to other applications in the same realm.7h CVE-2026-20535—

——0ZITADEL 3.x before 3.4.15 and 4.x before 4.17.1 contains an improper authorization vulnerability: when issuing passkey or passwordless enrollment codes, it checks only the organization in the x-zitadel-orgid header, not the target user's organization. Attackers with user-write permission in one organization can obtain an enrollment code for a user in another organization on the same instance and register their own authenticator to take over that account.22h CVE-2026-945058.1 ALT

——6The Nelio Content – Editorial Calendar & Social Media Auto-Posting plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 4.5.0 This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with contributor-level access and above, to permanently delete any reusable social message (nc_reusable_social post), including those authored by administrators or other privileged users.2d CVE-2026-116015.3 MED

——8The WPCafe – Restaurant Menu, Online Food Ordering & Table Booking System plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 3.0.19. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to read, create, update, clone, and delete email notification flows, including overwriting the default reservation confirmation, cancellation, and admin alert emails with attacker-controlled content sent from the site's legitimate address, or destroying reservation notification flows entirely. The vulnerable endpoints are active by default on every WPCafe installation without any configuration requirement, as the Email_Automation_Service_Provider::is_enable() method unconditionally returns true and the plugin ships with five pre-configured default email flows upon activation.2d CVE-2026-924375.3 MED
