How a Harmless Query Can Hijack LLM Agents: The First Semantic Cache Key Collision Attack

A new study presented at ICML 2026 reveals that the fuzzy matching used in LLM semantic caching creates an integrity vulnerability, allowing attackers to craft adversarial suffixes that cause cache‑key collisions and achieve up to 86 % response‑hijacking success on major cloud services such as AWS and Azure.

Zero‑Shot Dual‑Arm Robot Learning from 30 Minutes of Human Egocentric Video (HumanEgo)

HumanEgo shows that a single 30‑minute egocentric video captured with a wearable Aria camera can train a dual‑arm robot to achieve 92.5% success on four real‑world tasks, transfer zero‑shot across robots, cameras and environments, and outperform tele‑operation while requiring far less data.

Can Transformers Solve Any Computable Problem? RUC Study Shows Context Management Sets the Upper Bound

A recent ICML 2026 position paper clarifies that the computational power of a fixed Transformer model is limited by its context‑management strategy, distinguishing fixed‑system and scaling‑family settings and showing how five concrete management approaches span from constant‑space to full Turing‑completeness.
