Critical RCE in Langflow (CVE‑2026‑33017) and Trivy Supply‑Chain Compromise (CVE‑2026‑33634) Prompt Immediate Federal Action

CISA added two newly disclosed flaws to its catalog: a critical unauthenticated RCE in Langflow and a malicious‑code injection in Aqua Security’s Trivy scanner. Both are being weaponised in the wild, exposing credentials and threatening downstream supply‑chain integrity for organisations that rely on these open‑source tools.

Critical RCE in Langflow (CVE‑2026‑33017) & Trivy Supply‑Chain Compromise (CVE‑2026‑33634) Threaten AI Workflows and Container Scanning

What It Is – Two high‑severity vulnerabilities were added to CISA’s Known Exploited Vulnerabilities catalog. CVE‑2026‑33017 is a critical unauthenticated remote‑code‑execution flaw in Langflow 1.8.2 and earlier. CVE‑2026‑33634 is a malicious‑code injection in Aqua Security’s Trivy scanner that enables a supply‑chain compromise.

Exploitability – Langflow’s flaw was weaponised within 20 hours of advisory publication; attackers built exploits without a public PoC and began scanning the Internet. Trivy’s backdoor was observed in the wild on March 19 2026, attributed to the TeamPCP threat group. Both are actively exploited.

Affected Products – Langflow (open‑source AI‑agent framework, ≤ v1.8.2). Aqua Security Trivy (container image scanner, all versions containing the malicious payload).

TPRM Impact –

  • Credential theft from compromised Langflow instances can cascade to downstream databases and SaaS services.
  • Trivy’s supply‑chain breach can inject malicious code into any CI/CD pipeline that relies on its scanning results, affecting downstream applications and customers.

Recommended Actions –

  1. Prioritise patching Langflow to ≥ v1.8.3 and apply the Trivy remediation released by Aqua Security.
  2. Conduct immediate inventory of all third‑party services that consume Langflow APIs or Trivy scan results.
  3. Deploy network segmentation and runtime detection to limit lateral movement from compromised instances.
  4. Review and rotate any credentials or API keys exposed in logs or environment variables.
  5. Update incident‑response playbooks to include rapid‑patch windows for zero‑day disclosures.
