CVE-2025-59434

🚨 A free-tier user can access sensitive secrets from other tenants in Flowise Cloud — a recipe for disaster! 🔥 Think of Flowise Cloud as a bustling hotel where guests can leave their valuables in safekeeping. Unfortunately, a janitor (the Custom JavaScript Function node) has the keys to every room, allowing them to sneak a peek at any guest's private stuff without anyone knowing! An attacker on the free tier could easily swipe sensitive information like OpenAI API keys, AWS credentials, and Google Cloud secrets, leading to catastrophic consequences including unauthorized access to valuable resources and data leaks. This full cross-tenant data exposure could not only harm your business but also jeopardize customer trust and security.

An attacker on the free tier could easily swipe sensitive information like OpenAI API keys, AWS credentials, and Google Cloud secrets, leading to catastrophic consequences including unauthorized access to valuable resources and data leaks. This full cross-tenant data exposure could not only harm your business but also jeopardize customer trust and security. Update your Flowise Cloud to the patched version released in August 2025 immediately. Review and restrict permissions for the Custom JavaScript Function node to prevent similar exposures moving forward. Additionally, audit your environment variables to ensure no sensitive data is inadvertently exposed. You've got this! By taking these steps, you'll tighten up your security and protect your data like a true hero! 🛡️
