What happened

Collection of new 2026 arXiv papers exposing and addressing security risks in LLM-driven agents and related systems. Key offensive findings: MemMorph demonstrates high-success memory-poisoning attacks that bias long-term memory to hijack tool selection (up to 85.9% success with only three poisoned records); BITE shows black-box stylistic-edit attacks that inflate LLM-judge scores; Furina reveals an instability region in safety/refusal behavior enabling robust jailbreaks via uncertainty amplification. Other contributions: AgentSecBench formalizes measurement/games for instruction/retrieval/cap-
