Ajar: Measuring Open Privilege in Agent Defenses An agent-security benchmark reports two numbers, attack success and benign utility, and both are read off runs that happened. Neither says what the defense stood ready to allow on the paths no run took. Ajar asks it directly: for each benign task i...

Sapien: A Stateful Policy Engine for Autonomous AI Agents

Contextual security defenses prevent AI agents from taking rogue actions by synthesizing a task-specific policy and enforcing it on the agent's tool calls. In multi-step tasks, however, which actions are valid often depends on what the agent has already done and learned. We present Sapien, a poli...

CVE-2026-82579

Loop with Unreachable Exit Condition Infinite Loop vulnerability in ash-project ashai allows an attacker who can influence a model's output to hang the tool loop and drive unbounded, repeated model requests. AshAi.ToolLoop classifies a model response of :toolcalls, then filters the calls through...

CVE-2026-82579

CVE-2026-82579 is an infinite loop vulnerability in the ash_ai Elixir/Erlang library (versions 0.6.0 through before 1.0.0 ), affecting the AshAi.ToolLoop component. When all tool calls are filtered out—either due to a missing valid name or a reused tool_call_id—the loop recurses with a byte-ident...

CVE-2026-65975 Pydantic AI AG-UI Adapter: A dangling client-submitted tool call can execute when a trailing message is dropped during `sanitize_messages`

Pydantic AI is a Python agent framework for building applications and workflows with Generative AI. In versions 1.88.0 up to but not including 1.107.1 and 2.0.0b1 up to but not including 2.5.0, the UI adapters AG-UI via Agent.toagui/AGUIAdapter, and Vercel AI via VercelAIAdapter use...

CVE-2026-65975

CVE-2026-65975 affects Pydantic AI AG-UI Adapter (AG-UI via Agent.to_ag_ui()/AGUIAdapter and Vercel AI via VercelAIAdapter) in Pydantic AI versions 1.88.0–1.107.0 and 2.0.0b1–2.4.x. The bug arises because sanitize_messages uses a stripping index computed before sanitization, so when a trailing cl...
