CVE-2026-50085
HighCVSS 8.6Exploitation Probability (EPSS)
Low risk20th percentile - higher than 20% of all known CVEs
Summary
The Aqara Board service (op-test.aqara.com) accepts arbitrary MQTT command payloads and forwards them to the HiveMQ broker without authentication. This is a missing authentication for critical function (CWE-306) with an estimated CVSS of 8.6 (High). Combined with other vulnerabilities, it can lead to fully unauthenticated remote takeover of affected devices.
Risk Assessment
An attacker can remotely send unauthorized MQTT commands, enabling device manipulation and potential full takeover, compromising confidentiality, integrity, and availability of the system.
Recommendation
Immediately implement authentication for all MQTT connections to the Aqara Board service and restrict access to the HiveMQ broker to authorized clients only.

- 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.
- CVE-2026-16310Critical
The MemberDash plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to and including 1.8.5 via the 'id' parameter due to missing validation on a user-controlled key. This allows unauthenticated attackers to change the password of any WordPress user, including administrators, by supplying an arbitrary user ID during registration, and take over their account without any notification to the victim.
