CVE-2026-91987

atomic-agents-stack before 1.1.0 contains a cost-guardrail bypass in the estimatebatchcost function that returns zero cost for unknown models not in the pricing table. Attackers can configure deployments with unknown model identifiers to bypass daily cost caps and exceed budget limits in parallel...

CVE-2026-91987

atomic-agents-stack before 1.1.0 is affected by a cost-guardrail bypass in the _estimate_batch_cost function (agent.py). The function looks up per-model output price via PRICING.get(model, {}), which returns 0.0 for any model not in the hardcoded pricing table. When the reservation is ≤ 0, _check...
