    #NØØT_Security_Alerts 🚨 #ALERT — CRITICAL LANGFLOW FLAW ENABLES HOST CODE EXECUTION AND SUPERUSER TAKEOVER September 28, 2026 DISCLOSED BY: Langflow Security Maintainers / XlabAI Research PRODUCT: Langflow — AI Workflow Platform CVE: CVE-2026-10561 GHSA: GHSA-8qpj-27x8-pwpq SEVERITY: Critical — CVSS 9.9 AFFECTED VERSIONS: Langflow before 1.10.1. Fixed in 1.10.1; further hardened through 1.12.3. IMPACT: Insufficient isolation in PythonREPLComponent and PythonREPLToolComponent allows arbitrary Python execution with Langflow service privileges. Attackers can execute OS commands, access application data and elevate their accounts to superuser through database manipulation. EXPOSURE: Requires an authenticated user able to edit and execute flows containing the vulnerable interpreter components. EXPLOITATION STATUS: PUBLIC RESEARCH PoC. Maintainers document a working privilege-escalation technique. No confirmed malicious in-the-wild exploitation. Forensic triage: Review unexpected Python Interpreter flow executions, suspicious service subprocesses, unauthorized database changes and modifications to is_superuser account attributes. No confirmed campaign-specific IOCs. URGENT ACTION: Upgrade to Langflow 1.12.3 or later. Disable interpreter execution where unnecessary. Use microVM isolation for untrusted code and enforce least-privilege service credentials. SOURCE: https://github.com/langflow-ai/langflow/security/advisories/GHSA-8qpj-27x8-pwpq CONFIDENCE: HIGH — Maintainer-confirmed vulnerability, documented PoC and upstream security fixes. #CyberSecurity #ThreatIntel #Langflow #AISecurity #RCE #PrivilegeEscalation

    Post summary

    Official security advisory for CVE-2026-10561, a critical RCE/privilege escalation flaw in Langflow with a public PoC, named fixes in 1.10.1+, specific workarounds, but no confirmed in-the-wild exploitation.

    Running Langflow anywhere reachable from the internet? Two critical bugs to patch today 🧵 1/ CVE-2026-8505: in Langflow 1.7.0 through 1.9.0, webhook endpoints skipped the API key check by default. Anyone who knew a flow's ID could run it as you. Fixed in 1.9.1. https://vibevulns.com/issues/cve-2026-8505-langflow-webhook-auth-bypass-unauthenticated-flow-execution/?v=2 2/ CVE-2026-10561: before 1.10.1, the Python Interpreter component had no real sandbox. Any logged-in user who could edit a flow could run OS commands and make themselves superuser. https://vibevulns.com/issues/cve-2026-8505-langflow-webhook-auth-bypass-unauthenticated-flow-execution/?v=2 3/ Fix: upgrade to 1.12.3+ (the maintainers' recommendation), don't set LANGFLOW_WEBHOOK_AUTH_ENABLE=false, and turn off the interpreter if you don't use it (LANGFLOW_BLOCK_CODE_INTERPRETER_COMPONENTS=true).

    Post summary

    The text announces two critical Langflow vulnerabilities (CVE-2026-8505 and CVE-2026-10561) with technical details on auth bypass and sandbox escape, and emphasizes patching through specific version upgrades and configuration workarounds. The primary focus is on remediation actions.
