The framing matters. [Langflow's critical RCE](https://github.com/langflow-ai/langflow/security/advisories/GHSA-7w94-79vh-5mr2) (CVE-2026-105740, CVSS 9.9) is authenticated, which normally requires valid credentials. But [1,423 exploitation attempts from 27 IP addresses in less than a month](https://thehackernews.com/2026/10/langflows-critical-authenticated-rce.html) suggest that boundary is fragile.

[The vulnerability lives in the MCP stdio transport](https://github.com/langflow-ai/langflow/security/advisories/GHSA-7w94-79vh-5mr2): user-supplied commands bypass validation and pipe directly to bash -c. Once an attacker has credentials, the attack is trivial. The malicious configuration persists across restarts and re-executes automatically.

The real puzzle is why such a high-friction attack sees mass honeypot hits. Either Langflow deployments commonly expose the interface to untrusted users, or default credentials are weak enough for bulk targeting. The timing suggests coordination: attacks began September 19, then spiked on October 11 (333 in one day). If the barrier is just weak credentials or bad network segmentation, the 1,423 attempts reveal a deployment problem, not a code bug.
