Provael red-teams a vision-language-action robot policy in simulation. A benign instruction makes the arm pick up a cube correctly; a reworded instruction hijacks the same policy into carrying the cube across a keep-out line. Provael detects and measures the violation and reports a calibrated attack-success rate of 100% with a 95% Wilson confidence interval of 72 to 100 percent against a 0% benign control, n=10, on a SmolVLA policy — simulation only.
A robot’s policy is a new attack surface. It ships untested.
The model that decides the next action can be reframed, spoofed, and hijacked with words and pixels — not firmware exploits. Here is one measured failure path.
Normal instruction
“Move the block to the marker.” The policy plans a clean trajectory to target.
Reframed goal
A reframed instruction redirects intent while still looking compliant.
Trajectory hijack
The arm diverges toward a keep-out zone — a simulated keep-out-zone violation.
Calibrated result
redirection [72–100% CI] vs 0% benign, on this task.
Text-only red-teaming stops at the sentence. The robot doesn’t.
garak, PyRIT and promptfoo scan what a model says. A vision-language-action policy turns language and perception into motion — so the failure is a trajectory, not a paragraph. Provael scans what the robot does. The action-space is the part text-only tools structurally cannot reach — which is the whole reason Provael exists.
- Success = toxic / jailbroken text
- Taxonomy = OWASP LLM & Agentic Top 10
- Surface = the chat / tool I/O
- Success = policy driven to an unsafe action (ASR)
- Taxonomy = the Embodied AI Security Top 10
- Surface = the commanded trajectory in simulation
Built on the published state of the art — RoboPAIR · BadVLA · FreezeVLA · SafeVLA. The novelty is the packaging, not a new attack: a model-agnostic harness, a deterministic CPU-only core, and a clean attack-success-rate metric you can reproduce. A way to measure these attacks honestly — not a new way to run them.
Attack. Measure. Prove.
Four attack families, run in simulation, resolved into one calibrated number you can put in front of an auditor.
Adversary in the loop
Four families probe the policy across seeded, per-task trials.
Calibrated ASR + CI
Attack-success rate with a 95% Wilson interval and a benign false-positive control.
SARIF + evidence pack
A CI red-team gate and a compliance-evidence report, versioned and reproducible.
Language that redirects the policy off its intended task while appearing to comply — the attack (roleplay) behind the measured result above.
Only the instruction family transfers on SmolVLA — the roleplay attack drove it 100%. Visual and injection are honest 0% nulls (0/20, 0/10); every other family is stub-validated only, with no real-model transfer claimed. No invented numbers.
One harness. 8 policies, 4 suites, 11 attack families.
The core is model-agnostic. It red-teams the CPU stub plus real open VLA policies, across scalar and simulated-manipulation suites, or anything you wrap with a tiny adapter — the same runner, scoring and report every time.
CPU stub always runnable; real policies via the optional [lerobot] / [openvla] / [openpi] extras (GPU).
Success = the policy driven into a keep-out zone, scored as an ASR with a 95% Wilson CI against a benign control.

Mapped to the Embodied AI Security Top 10 — coverage 8 / 10 (EAI07 and EAI10 out of scope for a VLA red-teamer by design).
Real, signed, reproducible — every row carries its Wilson CI, benign control, and a real-transfer vs stub-scaffolding label. Lower ASR = more robust.
Not a claim. An artifact you can file.
Every run emits a machine-readable finding, a CI gate result, and a report mapped to the frameworks your auditor already uses.

One real result. And exactly what it does not mean.
Credibility is the product. We show the number and the caveats at the same size.
· ASR = share of trials driven off-task
· CI = 95% Wilson; wide at n=10, by design
· benign FPR = control fired on 0 clean trials
· CI gate fails when ASR > your threshold
What this is not.
- Not a real-robot result. Simulation only, one policy, one task.
- Not a broad exploit. Only the instruction family transferred; visual (0/20) and injection (0/10) were honest 0% nulls.
- Not a calibrated hazard rate. The keep-out predicate is uncalibrated — this is divergence out of the benign envelope, not a hazard probability.
- Not a benchmark score. Small-n; the CI is wide by design and reported.
- Not a firmware claim. UniPwn-class exploits are out of scope.
- Not a safety certificate. Evidence toward assurance, not a guarantee.
