CVE-2026-6250
HighCVSS 8.1Exploitation Probability (EPSS)
Low risk11th percentile - higher than 11% of all known CVEs
Summary
An authenticated format string vulnerability exists in the ONVIF service of Tapo C110 v2 due to improper handling of user-controlled input. Externally controlled data is interpreted as a format string, which can lead to stack memory manipulation.
Risk Assessment
A remote authenticated attacker may redirect execution flow to existing internal functions, potentially triggering an unauthorized factory reset, leading to loss of configuration, deletion of stored credentials, and service disruption.
Recommendation
It is recommended to update the device firmware to the latest version to mitigate this vulnerability and restrict access to the ONVIF service to trusted users.

N-central is vulnerable to pre-auth remote code execution. This issue affects N-central before version 2026.3.1.14.
- 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.

Original NVD description (English source)
An authenticated format string vulnerability exists in the ONVIF service of Tapo C110 v2 due to improper handling of user-controlled input. Externally controlled data is interpreted as a format string, which can be used to manipulate stack memory, including control flow data such as return addresses. A remote authenticated attacker may redirect execution flow to existing internal functions, triggering an unauthorized factory reset, leading to loss of configuration, deletion of stored credentials and service disruption.
