——0The AI Copilot – Content Generator plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.5.6. 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 create a new administrator-level user account and achieve full site takeover by saving and executing a malicious workflow containing a wp_create_user action node specifying role=administrator. This vulnerability is exploitable by unauthenticated attackers on any site where the [aiwu-form] shortcode or public chatbot is rendered on a frontend page, as the waic-nonce value is emitted into publicly accessible JavaScript (WAIC_DATA.waicNonce) on those pages, rendering the nonce check a non-functional authorization barrier.9hCVE-2026-152158.8 HIG8.2%
——2The Subscriptions for WooCommerce WordPress plugin before 2.0.1 does not verify the user's capability before installing and activating a Subscriptions for WooCommerce WordPress plugin before 2.0.1 from a user-supplied slug through a nonce-protected AJAX action, allowing users with the Shop Manager role (who lack Subscriptions for WooCommerce WordPress plugin before 2.0.1-management capabilities) to install and activate arbitrary Subscriptions for WooCommerce WordPress plugin before 2.0.1, resulting in remote code execution.21hCVE-2026-191897.8 HIG1.5%
——0A security flaw has been discovered in Power Sofware PowerISO 9.3.0.0. Affected by this issue is some unknown functionality in the library C:\Windows\System32\drivers\scdemu.sys of the component Kernel Driver. The manipulation results in improper privilege management. The attack is only possible with local access. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.1dCVE-2026-480869.9 CRI26.0%
——8OpenReception's appointment booking software provides an end-to-end encrypted appointment booking platform. Prior to version 1.0.2, a TENANT_ADMIN promotes themselves to platform-wide GLOBAL_ADMIN through a single PUT request. The role-update handler accepts the `GLOBAL_ADMIN` enum value from any tenant admin updating their own tenant's staff. No policy check enforces that "only an existing GLOBAL_ADMIN may grant GLOBAL_ADMIN", so the schema validation IS the authorization decision. After re-login, the JWT contains the new role and the formerly-tenant-scoped admin reaches every other tenant on the platform. On the hosted OpenReception service this is a scope-changed escalation: a single customer-side tenant administrator gains full platform-wide administrative control over all other tenants' configuration, users, staff records, operational metadata, and tenant lifecycle. Plaintext appointment contents remain subject to the E2E model unless chained with the staff-crypto poisoning issue (V-4) or with staff-passkey hijacking (V-1). On a single-tenant self-hosted deployment it is still a privilege escalation because TENANT_ADMIN should not be able to create new tenants, modify global configuration, or manage other administrators. The same handler also accepts updates targeted at any colleague within the tenant. A tenant admin can promote a separate collaborator account instead of themselves, leaving their own audit trail clean while the platform-wide breach happens through a separate identity. Version 1.0.2 fixes the issue.1dCVE-2026-17289.8 CRI21.9%
——7Tokens issued to a low-privileged user are not sufficiently restricted, allowing them to be used to access product-level Admin REST APIs.
Exploitation of this vulnerability allows a low-privileged user to invoke the Admin REST APIs of WSO2 products, potentially leading to full administrative account takeover. This requires the attacker to already possess a low-privileged user account and be able to obtain a valid token for it.2dCVE-2026-190076.3 MED11.2%
——3A vulnerability was determined in mf-yang openclaw-cn up to 0.2.1. This vulnerability affects the function isApprovedElevatedSender of the file src/auto-reply/reply/reply-elevated.ts. This manipulation causes improper privilege management. It is possible to initiate the attack remotely. The exploit has been publicly disclosed and may be utilized. The project was informed of the problem early through an issue report but has not responded yet.2d
