Agent-building frameworks are high-value RCE targets — Langflow's repeat CISA-KEV listings
Added 2026-07-14 · Last verified 2026-07-14
Langflow — a popular open-source visual framework for building AI agents and RAG pipelines — has had multiple critical flaws added to CISA's Known Exploited Vulnerabilities catalog over the past year (unauthenticated `exec()` RCE, an account-takeover token chain, and an IDOR that reads other tenants' flows). Attackers moved within ~20 hours of one disclosure, before any public PoC. The lesson for agent engineering: an agent-building platform is a concentrated credential store — it holds model API keys, cloud credentials, and DB strings — so a single authz gap (an ID that isn't checked against the caller, or code passed to `exec()` before auth) doesn't leak one secret, it leaks the whole ring. Harden agent frameworks like production infrastructure: authenticate AND authorize every flow/tool endpoint (deny-by-default), never expose them directly to the internet, scope secrets per tenant/agent with short-lived tokens, and treat any exposed instance as potentially compromised even after patching.
