CVE-2011-4860
HighSummary
Funkcja ComputePassword w module Ethernet Quantum firmy Schneider Electric na urządzeniu NOE 771 generuje hasło dla konta fwupgrade na podstawie adresu MAC. To umożliwia zdalnym atakującym uzyskanie dostępu poprzez wiadomość ARP lub wiadomość Neighbor Solicitation.
Risk Assessment
Organizacja może być narażona na nieautoryzowany dostęp do systemu, co może prowadzić do poważnych konsekwencji w zakresie bezpieczeństwa i integralności danych.
Recommendation
Zaleca się zabezpieczenie dostępu do urządzenia oraz monitorowanie i ograniczenie komunikacji ARP i Neighbor Solicitation w sieci.

The TrueBooker – Appointment Booking and Scheduler System plugin for WordPress in all versions up to and including 1.2.3 is vulnerable to authorization bypass. This is due to the plugin not properly verifying that a user is authorized to perform an action. This allows unauthenticated attackers to modify the email address of arbitrary user accounts, including administrators, which can be leveraged to reset the account password and gain access.
- CVE-2026-12793Critical
The JetFormBuilder — Dynamic Blocks Form Builder plugin for WordPress in all versions up to and including 3.6.2 is vulnerable to Privilege Escalation. This is due to the plugin not validating that a submitted form ID belongs to a JetFormBuilder form before parsing the referenced post's content as form schema and executing an Advanced Validation server-side callback. This allows unauthenticated attackers to create a new administrator-level user account.

`@zereight/mcp-gitlab` is a Model Context Protocol server for GitLab. Prior to version 2.1.27, the SSE transport mode (`SSE=true`) exposes all MCP tools without any authentication. The `upload_markdown` tool reads arbitrary files from the server's local filesystem via an unsanitized `file_path` parameter and uploads them to a GitLab project.
Original NVD description (English source)
The ComputePassword function in the Schneider Electric Quantum Ethernet Module on the NOE 771 device (aka the Quantum 140NOE771* module) generates the password for the fwupgrade account by performing a calculation on the MAC address, which makes it easier for remote attackers to obtain access via a (1) ARP request message or (2) Neighbor Solicitation message.
