An authenticated virtual machine escape vulnerability exists in HashiCorp Vagrant versions 2.4.6 and below when using the default synced folder configuration. By design, Vagrant automatically mounts the host system’s project directory into the guest VM under /vagrant (or C:\vagrant on Windows). This includes the Vagrantfile configuration file, which is a Ruby script evaluated by the host every time a vagrant command is executed in the project directory. If a low-privileged attacker obtains shell access to the guest VM, they can append arbitrary Ruby code to the mounted Vagrantfile. When a user on the host later runs any vagrant command, the injected code is executed on the host with that user’s privileges. While this shared-folder behavior is well-documented by Vagrant, the security implications of Vagrantfile execution from guest-writable storage are not explicitly addressed. This effectively enables guest-to-host code execution in multi-tenant or adversarial VM scenarios.

An authenticated local file inclusion vulnerability exists in Microweber CMS versions < 1.2.11 through misuse of the backup management API. Authenticated users can abuse the /api/BackupV2/upload and /api/BackupV2/download endpoints to read arbitrary files from the underlying filesystem. By specifying an absolute file path in the src parameter of the upload request, the server may relocate or delete the target file depending on the web service user’s privileges. The corresponding download endpoint can then be used to retrieve the file contents, effectively enabling local file disclosure. This behavior stems from insufficient validation of user-supplied paths and inadequate restrictions on file access and backup logic.

A new threat vector exploits how modern browsers save HTML files, bypassing Mark of the Web and giving attackers another social-engineering attack for delivering malware.

The Scattered Spider hacking group has caused chaos among retailers, insurers, and airlines in recent months. Researchers warn that its flexible structure poses challenges for defense.

Threat actors with ties to North Korea have been observed targeting Web3 and cryptocurrency-related businesses with malware written in the Nim programming language, underscoring a constant evolution of their tactics. "Unusually for macOS malware, the threat actors employ a process injection technique and remote communications via wss, the TLS-encrypted version of the WebSocket protocol,"
