CISA adds exploited Langflow remote-code-execution flaw CVE-2026-0770 to KEV and orders federal agencies to patch

CISA warned that attackers are actively exploiting a critical flaw in Langflow, an AI workflow framework, and told U.S. federal agencies to fix it by Friday. The bug, CVE-2026-0770, allows unauthenticated remote code execution as root via the /api/v1/validate/code endpoint through the exec_globals parameter. KEVIntel observed exploitation attempts and payloads aimed at reconnaissance, malware delivery, and theft of AWS credentials, environment variables, and container metadata.
Why it matters: Organizations running internet-exposed Langflow servers may already be at risk of full server compromise and cloud credential theft. Patch or isolate affected systems immediately, review logs for requests to the validation endpoint, and rotate potentially exposed secrets if compromise cannot be ruled out.
