Exploit Title: Langflow 1.8.1 - Unauthenticated Remote Code Execution (RCE)
Date: 2026-03-21
Exploit Author: Americo N. F. Simoes (SimoesCTT)
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.

- 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.
- 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.
- 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.
- Usage: The Sovereign Snap
