Security Bulletin: Authentication Bypass in Webhook Endpoints Allowed Unauthorized Flow Execution

Summary A vulnerability in the webhook authentication logic allowed unauthenticated users to trigger execution of any flow. The system incorrectly bypassed API key validation when the WEBHOOKAUTHENABLE configuration was set to False the default setting, allowing remote attackers who knew a flow's...

AI Agent Exploits Langflow RCE to Automate Database Ransomware Attack

Security firm Sysdig says it has found what it believes is the first ransomware attack run from start to finish by an AI agent. Its Threat Research Team calls the operator JADEPUFFER and says a large language model handled the whole job: breaking in, stealing credentials, moving deeper into the...
