CVE-2026-4621 MEDIUM This Month

NEC Aterm wireless router series (including WG1200HP2, WG1900HP, WG1800HP3, WG1200HP4, and nine other models) contain hidden telnet functionality that can be remotely enabled by unauthenticated network attackers via unspecified means, classified as CWE-912 (Hidden Functionality). The vulnerability carries a CVSS 6.3 score reflecting network-accessible attack vector with high complexity requirements and limited confidentiality/integrity impact. No public exploit code or active exploitation via CISA KEV has been confirmed at analysis time, though the remote enablement of administrative telnet access represents a significant privilege escalation pathway for subsequent unauthorized system access.

CVE-2026-33280 HIGH This Week

BUFFALO Wi-Fi router products contain hidden debugging functionality that permits authenticated attackers with high-level privileges to execute arbitrary operating system commands remotely. The vulnerability affects an unspecified range of BUFFALO's router lineup and carries a CVSS score of 7.2, requiring high privileges (PR:H) but low attack complexity over the network. No public exploit identified at time of analysis, and EPSS data is not provided in available intelligence.

CVE-2026-31847 HIGH This Week

A hidden functionality vulnerability exists in the /goform/setSysTools endpoint of Nexxt Solutions Nebula 300+ firmware through version 12.01.01.37, allowing unauthenticated remote attackers to enable a Telnet service that exposes a privileged diagnostic management interface. This significantly expands the attack surface and enables further device compromise through an unencrypted network protocol. No CVSS score, EPSS data, or KEV status is currently available, but the severity is elevated given the remote nature of exploitation and the direct access to privileged diagnostic functions.

CVE-2026-3587 CRITICAL CISA Act Now

A hidden function in the CLI prompt of multiple WAGO industrial and lean managed switches allows unauthenticated remote attackers to escape the restricted interface and gain root access to the underlying Linux operating system. This results in complete device compromise with a maximum CVSS score of 10.0. The vulnerability affects over a dozen WAGO switch models used in industrial automation environments, and was disclosed by CERT@VDE.
