Summary
Connected IO version 2.1.0 and prior has a misconfiguration in their MQTT broker used for management and device communication. This allows devices to connect to the broker and issue commands to other devices, impersonating the Connected IO management platform.
Risk Assessment
The organization may be exposed to unauthorized commands issued by devices, potentially leading to serious security and integrity issues within the system. Potential attacks could affect all Connected IO devices on the network.
Recommendation
It is recommended to upgrade to the latest version of Connected IO and review the configuration of the MQTT broker to secure communication between devices. Additionally, implement further authentication and authorization mechanisms.

- CVE-2026-75816Critical
The Frontend Admin by DynamiApps plugin for WordPress is vulnerable to Authentication Bypass to Account Takeover in all versions up to and including 3.29.12. The pre_update_value function lacks capability or ownership checks, and ActionPost::conditions_logic() short-circuits the current_user_can('edit_post') authorization gate when the post ID is non-numeric, allowing unauthenticated form submissions to be routed to arbitrary user records. This enables unauthenticated attackers to overwrite any user's email address, including an administrator's, and then use WordPress's native password-reset flow to take over the account.
