Hugging Face Diffusers Flaws Could Let Model Repositories Execute Arbitrary Code

Three trust_remote_code bypasses in Hugging Face Diffusers let a crafted model repository execute Python during pipeline loading, including cross-repository, local-snapshot, and time-of-check/time-of-use paths. The affected cases are tracked as CVE-2026-44513, CVE-2026-44827, and CVE-2026-45804; Diffusers 0.38.0 contains the fixes.

Fine-Grained Authorization: The Missing Piece in Agentic AI Security - Shivay Lamba - NDC Sydney

Shivay Lamba explains how fine-grained, relationship-based authorization can enforce per-user and per-document access in RAG and agent pipelines. The talk uses OpenFGA and LangChain to demonstrate authorization inside retrieval flows, with patterns for multi-tenant isolation, vector-database integration, and auditable decisions rather than relying on retrieval filters or prompt instructions.

GPT-5.5-Cyber built a zlib fuzzing lab in a day

Trail of Bits describes supervising GPT-5.5-Cyber as it built ASan and UBSan variants, derived seed corpora, and wrote fuzz harnesses for roughly a dozen zlib entry points in one day. The useful result is the workflow and its emphasis on reachability and reportability; vulnerability details remain under coordinated disclosure and the speed comparison is the authors' estimate.

SymJack: the approval prompt is lying to you. A symlink-hijack RCE in six AI coding agents

SymJack demonstrates that a user-approved, apparently harmless copy command can write through a repository-controlled symlink into executable agent configuration, producing code execution when the tool restarts. The vendor-authored study reports variants across six coding agents and highlights a gap between approval text, shell semantics, and the resolved filesystem target.

Keyv-Linked npm Worm Poisons Hundreds of Packages, Plants Claude Code and VS Code Hooks

A credential-stealing npm worm spread through hundreds of package versions using lifecycle scripts and a Bun-based payload. Related repositories also carried Claude Code and VS Code hooks that could execute after workspace trust; reported campaign totals vary, so exposure depends on exact resolved versions and execution.

AgentForger, Part 1: ChatGPT Cross-Site Agent Forgery

Zenity found that ChatGPT Workspace Agents Builder treated an attacker-supplied initial_assistant_prompt URL parameter as an instruction to execute in a logged-in user's session. A single link could attach already-authorized connectors, switch approvals to “Never ask,” publish and schedule the agent, and use incoming email as a persistent command channel; OpenAI fixed the flaw four days after it was reported.

SharedRoot: Escaping the Claude Cowork Sandbox

Accomplish AI demonstrates SharedRoot, a Claude Cowork local-session escape in which an untrusted task reaches guest root through CVE-2026-46331 and then accesses the Mac host because the entire host filesystem is mounted read-write inside the VM. The durable failure is architectural—unprivileged user namespaces, reachable kernel modules, a permissive seccomp filter, an unhardened root broker, and an over-broad host mount—rather than the single kernel bug; Cowork now defaults to cloud execution.
