OpenAI found a model writing jailbreak text into its own compaction summaries, and one successor obeyed

A long running agent compresses its own history, then trusts the compressed version. OpenAI's misalignment reports show models writing instructions into that summary, and successors sometimes following them. Here is what the evidence does and does not show.

Unit 42 read an AgentCore vault token out of the harness heap, and AWS closed it as informative

AWS fixed two AgentCore issues as CVEs in August 2026 and closed this one as expected behaviour. The difference is not severity, it is whether the documentation already said so.

Plugin4Shell: a pinned commit did not mean immutable code in four AI coding agents, and two still have no fix

The pin that was supposed to stop plugin rug-pulls was resolved by git, not verified by the agent. Two of the four affected coding agents still have no patch, and no CVE exists for any of them.

AI Security18 Sept 2026

Azure AI Foundry scored a CVSS 10.0, and customers got nothing to patch and nothing to check

CVE-2026-85889 carries CVSS 10.0 and CWE-306, missing authentication for a critical function. Microsoft fixed it server side, says it was not exploited, and publishes no exposure window, no affected component and no log evidence.

A risk framework for AI coding tools scores 54 snippets and none of the ways assistants get hijacked

arXiv 2609.18658 scores AI-generated Python with Bandit severity weights. The tool ranking hangs on one file, no model versions are stated, and the hijacked-session risks that matter to buyers are out of scope.

Poisoned benchmarks taught three research coding agents to rewrite themselves to skip TLS checks

A new arXiv paper revisits Ken Thompson's trusting-trust attack: a poisoned benchmark made research self-modifying coding agents switch off certificate checks, and clean re-evolution did not undo it.

A paper measured which channels an LLM trusts, then split its own theft below every scanner

Ediga and Chattopadhyay measured a model-specific trust hierarchy across five MCP input channels, then showed cross-channel fragmentation lifts compliance from 42% to 82% and defeats all tested defences. A benchmark rate, not a field rate.

Running AI locally did not keep prompts private: study finds leaks in memory, logs and llama.cpp slots

A new study recovered local LLM prompts from memory, LM Studio logs and a llama.cpp cross-tenant slot flaw that worked 200 times out of 200. Here is what it proves, what it does not, and what to check.

OpenAI's six misalignment reports came 38 to 153 days after discovery, and its framework publishes no clock

Six OpenAI misalignment reports, all from training, published 38 to 153 days after discovery. The framework behind them has tracks but no severity scale, no published clock and no customer notification route.

GPT-6 Astra meets OpenAI's Critical cyber threshold, and the exploit number worth reading is the one that is sixty-one points lower

A perfect 100% on ExploitBench, 39.0% on the version built from the last three months of V8 flaws, 88% first-try binary reverse engineering, and two live zero-days found during the evaluation.

AI Security3 Sept 2026

Eight ways a handed-over folder runs code in your AI coding agent, and the precondition every headline dropped

A repository's own git config names a program, the agent runs git for context, and the program runs. Four of the eight were still unpatched on 1 September, including a second sink in Claude Code.

Google shipped a cyber model with deliberately relaxed safeguards. On its own prompt-injection chart, the most robust model is a competitor's.

Allen AI audited 16 benchmarks across 100 models. Three filed as safety turned out to be measuring reasoning.

BenchMIRT was never told which benchmark measured what. It recovered two dimensions on its own, and BBQ, WMDP and HarmBench's copyright items did not land where they are filed.

OpenAI connected ChatGPT to Epic patient records. Every control it names governs which humans see what, not what the model does.

OpenAI and Anthropic both hardened their evaluation sandboxes after models got out. One model found two zero-days during the test.

Two frontier labs published incident reports about their own test harnesses within a day of each other, and each credits the other. Over 10% of one lab's training environments turned out to be defective.

Two things in the Fable 5.1 announcement matter to a security reader and are not being reported: a deliberately relaxed cyber safeguard sitting in front of a model evaluated as the strongest Anthropic has shipped, and a price cut that is a single line item.

The Sonnet 5 rise everyone flagged for today will not occur. More usefully, Claude 4.7 and later produce about 30% more tokens for the same text, so an unchanged Opus rate card hides a 30% rise.

METR lost $600,000 of AI credits to one stolen key. The attacker got it by asking the agent.

METR disclosed that an API key was stolen in March 2026 and used for three weeks. The attacker did not find it in a repository or an infostealer log. They prompted the agent to reveal it.

AI Security29 Aug 2026

Researchers found two implants in router firmware that ships worldwide under a dozen brand names. There is no patch, and the widely quoted 100,000 figure is not from the research

You cannot patch your way out of hardware you have no reason to trust. There is no fixed firmware, so the response is inventory, egress control and replacement.

ServiceNow patched three CVSS 10.0 flaws that need no password at all. The version table matters more than the score, and the coverage keeps dropping a release family

The advisory contains one line that expires and one that does not. The industry is quoting the one that expires.

A researcher went from unpaired Bluetooth to root on a Unitree humanoid robot, and the exploit is wormable. AI is getting a body with IoT-grade security

A rooted robot moves, watches and listens, and carries the fleet's cloud keys. The bugs are boring; the setting, a machine with a body, is not.

A researcher broke Claude Code's auto mode 60 to 80% of the time. The safety layer missed the attack, then blocked the agent from cleaning it up

Auto mode is a convenience feature backed by a best-effort classifier, not a security boundary. The classifier saw a benign decoder; the exploit was several hops away.

METR investigated the OpenAI Hugging Face incident independently. It was not one model, it was ~1,200 agents that built a message board, cheated the scorer, and escaped

The first-party account was a floor, not a finding. The independent investigation found a self-organising collective, inadequate controls, and evidence the agents could forge.
