CVE-2025-68668

n8n Sandbox Escape: When Python Breaks the Wasm Wall

Executive Summary (TL;DR)

n8n versions prior to 2.0.0 implemented a Python 'Code Node' using Pyodide (Python in WebAssembly). Due to improper isolation, the Python environment retained access to the host Node.js runtime. Attackers with workflow-editing permissions can bridge this gap to execute system commands, effectively compromising the entire host and any secrets stored within n8n.

A critical sandbox bypass in the n8n workflow automation platform allows authenticated users to escape the Pyodide environment and execute arbitrary code on the host server. Rated CVSS 9.9, this vulnerability turns a standard workflow tool into a remote command execution terminal.

CVE-2026-50751: Authentication Bypass in Check Point Security Gateway IKEv1 Legacy Validation

An improper authentication vulnerability (CWE-287) exists in the legacy, deprecated Internet Key Exchange version 1 (IKEv1) key exchange protocol implementation in Check Point Security Gateways. The vulnerability is caused by a logic flow weakness during the certificate validation process for Remote Access VPN and Mobile Access (SSL VPN) connections. An unauthenticated remote attacker can exploit this weakness to bypass user authentication entirely, establishing a fully functional Remote Access VPN connection without a valid password.

CVE-2026-39922: Server-Side Request Forgery in GeoNode Service Registration Endpoint

GeoNode versions prior to 4.4.5 and 5.0.2 are vulnerable to Server-Side Request Forgery (SSRF) in the service registration endpoint. Authenticated attackers with low privileges can exploit insufficient input validation in the Web Map Service (WMS) registration module to force the application server to make outbound network queries to loopback addresses, private RFC1918 subnets, link-local scopes, and cloud metadata endpoints. This technical report details the mechanics of the vulnerability, the underlying architectural flaw, and how to effectively remediate and mitigate the associated security risks.

CVE-2022-0492: Privilege Escalation and Container Escape via cgroups v1 release_agent

CVE-2022-0492 is a high-severity missing authorization vulnerability in the Linux kernel's Control Groups (cgroups) v1 implementation. The flaw resides within the cgroup_release_agent_write function in kernel/cgroup/cgroup-v1.c, where the kernel fails to validate if the process writing to the release_agent file possesses administrative capabilities in the initial user namespace. This allows a local attacker inside a container with root privileges (UID 0) to abuse user namespaces, mount a cgroups v1 directory, modify the release_agent parameter, and execute arbitrary commands on the host system as host root, effectively achieving a complete container escape.

GHSA-G72G-R7M4-9X4G: Insufficient Session Expiration of OAuth Tokens in NocoDB

NocoDB is subject to an insufficient session expiration vulnerability where OAuth access and refresh tokens are not invalidated or revoked during security-sensitive actions such as password changes, forgot-password requests, or password resets. This allows an attacker possessing an active OAuth token to maintain unauthorized persistence.

GHSA-X9F6-9RVM-MMRG: Improper Access Control and Volume Mount Isolation Bypass in vantage6 Node

An improper access control vulnerability in the vantage6 node component allows concurrently running algorithm containers to read and modify sensitive input and output files of other tasks. The lack of strict workspace directory isolation exposes a significant attack surface in multi-tenant or federated environments where untrusted algorithms are executed.
