According to VulnCheck, threat actors are actively exploiting two critical vulnerabilities: CVE-2026-0768 in Langflow, which lacks input validation and could allow arbitrary Python code execution as root, and CVE-2026-66066 in Ruby on Rails. The full details of the Rails flaw were truncated in initial reporting, but both flaws are assessed as critical and have been weaponized in the wild for credential-probing and command-and-control activity.
Security researchers and threat actors are exploiting an unauthenticated remote code execution vulnerability in Langflow, an open-source framework for building AI applications. The flaw, tracked as CVE-2026-0768, allows unauthenticated attackers to execute arbitrary code on exposed instances, leading to the theft of credentials, tokens, and keys from integrated OpenAI and AWS services. The vulnerability was publicly reported in September 2026. Affected deployments include Langflow instances exposed to the internet. Mitigation guidance recommends updating to a patched version and restricting network exposure.
