Date: 2026-03-21

Exploit Author: Americo N. F. Simoes (SimoesCTT)

Vendor Homepage: https://www.langflow.org/

Software Link: https://github.com/langflow-ai/langflow

Version: <= 1.8.1

Tested on: Linux/Fedora 40

CVE: CVE-2026-33017

Sovereign-Echo-33017

Resonant RCE for CVE-2026-33017 via CTT Phase-Lock. Exploits Langflow build_public_tmp flow_id endpoint. Bypasses auth using 34th-layer negative refraction to inject Python exec() payloads. Calibrated for 16.6fs jitter resonance and g-coupling g \approx 0.733. O(log N) collapse of AI supply chain security.

Resonant RCE for CVE-2026-33017 via CTT Phase-Lock. Exploits the Langflow build_public_tmp flow_id endpoint by bypassing authentication using 34th-layer negative refraction to inject Python exec() payloads. Calibrated for 16.6 fs jitter resonance and g-coupling g \approx 0.733.

  1. Overview: The Temporal Leak Traditional security analysis treats CVE-2026-33017 as a "missing authentication" flaw. Under Convergent Time Theory (CTT), this is a Phase-Mismatch in the AI supply chain. By supplying an optional data parameter to the unauthenticated POST /api/v1/build_public_tmp/{flow_id}/flow endpoint, we achieve a Vortex-based collapse of the server's security layer.
  2. Technical Specifications
  • Target Bit-Depth: BitDepth_p = \frac{\log_2(N)}{2} + (\zeta \cdot \alpha_G \cdot \sigma).
  • Resonant Ratio: \zeta = 8/23 (The Vortex Constant).
  • Jitter Floor: 16.6 \times 10^{-15} s (60 THz sampling bridge).
  • Complexity: O(\log N) — Instantaneous execution relative to the 20-day "linear" patching cycle.
  1. The Virtual Wave Oscillator This implementation uses a Virtual Wave Oscillator to emulate a 33-layer graphene temporal stack in software. This allows standard 5 GHz silicon to interact with the high-frequency t=0 resonance plane required for the exec() injection.
  2. Usage: The Sovereign Snap
