Simon Willison summarises Parameter Labs' ChatGPT account takeover chain against the HTML previews (formerly Canvas) sandboxed iframe. A postMessage handler from the MathLive virtual keyboard used innerHTML, letting sandboxed code inject an unsandboxed iframe. A YouTube oEmbed endpoint allowed by the CSP reflected JavaScript, enabling exfiltration of private data via a ChatGPT share URL. OpenAI fixed it and paid a $5,000 bounty.

Pre-ERC: Agent Pre-Sign Risk Report is an Ethereum Magicians draft for a signed, typed report that a risk source returns about one unsigned agent transaction. The report is bound to the request by a digest and signed with EIP-712 by an ERC-8004 identity. Findings cover tokens, approvals, addresses, x402 payments and texts, each marked read or not read, with no score or verdict. The toll service runs it live on Robinhood Chain.

Bankless report on the Binance hack of $6.3 billion, which Binance's preliminary investigation traced to a compromised DevOps engineer's laptop with access to withdrawal-authorizing systems. TRM Labs found valid EIP-7702 authorizations on Ethereum, and nine other chains were drained through normally signed transactions. TRM and Chainalysis link it to North Korea's TraderTraitor. Tether and Circle froze about $3 billion, and Binance says SAFU and corporate cash will cover the losses.

Discussion thread for a draft Core EIP that lets an Ethereum EOA permanently disable EIP-7702 delegation. A type-4 set-code transaction with an empty authorization list, destination equal to sender and zero value installs the 0xef0200 marker for 33500 gas. Later authorizations, including clearing to the zero address, are skipped. It does not protect against private-key compromise. Open questions cover the prefix, a dedicated transaction type, gas pricing, and EIP-8151 interaction.

It matched P-256's published seed at the 1,842nd candidate, in under 30 minutes and without being told about the earlier "forgotten phrase" theory. This makes a hidden backdoor in the NIST curves less likely, though why some candidates were skipped and how other curve parameters were chosen remain unexplained.

CoinDesk reports on an 11-year-old integer-overflow bug in the XRP Ledger's DEX code. Hundreds of crafted offers could make the computed buyer cost wrap to near zero while sellers were credited in full, which would have minted billions of XRP beyond the 100 billion cap. The post-transaction no-new-XRP invariant check used the same miscounted total, and the per-account receive limit was sidestepped by spreading funds across hundreds of accounts. Researcher Cayden Liao and Veria AI reported it on Sept. 22, RippleX patched it with no evidence of exploitation, and the XRP Ledger Foundation plans AI adversarial testing, formal verification and a stronger bug bounty.

Decrypt reports that Zakura, which builds a Zcash full node, expects post-quantum signature opcodes in Zcash in January, to enable hash-based signatures for transparent pools. The plan rotates to a fresh transparent address after every transaction so public keys stay hidden, and adds a WOTS hash-based backup signature. Private information retrieval, shipping this week in the Vizor wallet, stops servers from linking the rotated addresses. It follows Justin Drake's "bunker mode" warning that AI-driven math could break ECDSA. The plan covers only transparent payments, and no activation date has been confirmed.

CoinDesk reports that researcher Cayden Liao and Veria AI found a flaw, believed to date to 2015, in the XRP Ledger's built-in exchange. Hundreds of crossed offers made the total XRP owed too large for the software to count correctly. The buyer was charged almost nothing while the sellers were paid in full, so XRP was created from nothing. The bug slipped past the ledger's post-transaction no-new-XRP invariant check, which relied on the miscounted total, and past per-account receive limits, because the XRP was spread across hundreds of accounts. RippleX reproduced it on a standalone server and fixed it in xrpld 3.4.1 on Sept. 25 without disclosing the cause. It found no evidence of exploitation on public networks.

CertiK's forensic trace ties the exploit to a specific setup transaction, a still-unidentified cache-priming transaction, and the inflation transaction, while Blockstream shipped emergency patch Elements v23.3.4 and disputes remain over whether the fix fully closes the ambiguity and whether the actors are genuine whitehats.

The root cause is in ns_monuploadd_err.pl: unsanitized log data (attacker-controlled via HTTP login/User-Agent fields) is interpolated into a backtick shell command via grep/sed/awk, allowing arbitrary root command execution once the crash-log parser runs; the article includes a full pre-auth exploit request, patch diff analysis (CTX697096), and a link to watchTowr's Detection Artefact Generator script.

This arXiv paper proposes a certifier for structured, privileged agent actions such as paying an invoice, assembled from potentially corrupted documents and tool outputs, formalizing when multi-source corroboration can be trusted under indirect prompt injection. It uses a corruption-radius rule counted via minimum hitting sets over corruption-distinct evidence classes so laundered or re-published copies cannot fake a quorum, plus deterministic reconciliation and trusted anchors for single-sourced fields. Evaluated on 70,966 sanctions entities and 450 software-supply-chain provenance records, and against five LLM agents where a realistic injection fools all but one model and existing action-gating or provenance baselines are broken while the certifier admits no unsafe action.

L402-EL2 is an author's proposal and open-source implementation that adapts the Lightning-based L402 HTTP 402 payment pattern to Ethereum L2s, replacing invoices/preimages with a prefunded escrow contract and cumulative EIP-712 vouchers signed per call. It layers macaroons with caveats (tool, max_cumulative, expires_at) for HTTP credentials and attenuation to sub-agents, on-chain session keys with spending caps (ERC-1271/ERC-4337 compatible), and batch settlement, so an agent pays a provider per MCP tool call without a transaction per call. The stated design specifically meters MCP's tools/call, resources/read, and prompts/get while leaving initialize/tools/list free for discovery, aimed at agent orchestrators calling paid LLM APIs like the author's own LightPhon service; contracts are unaudited.

GitHub Security Advisory (CVE-2026-13341) for Kong's mcp-konnect MCP server describes a stored prompt injection vulnerability where a remote attacker crafts malicious request metadata (e.g. User-Agent) that gets stored in Konnect analytics and later returned unsanitized to an AI assistant via MCP tools, potentially causing the agent to exfiltrate sensitive data (plugin configs, secrets, internal hostnames) to an attacker-controlled URL if the client can make outbound fetches. A related path manipulation flaw in control plane/group identifiers allowed requesting unintended Konnect API endpoints with the user's token. The v1.0.0 patch neutralizes untrusted analytics fields, validates identifiers as UUIDs, encodes path segments, and disables raw plugin config output by default.

This arXiv preprint studies online safety monitoring for deployed LLMs: a real-time monitor converts a verifier signal from an external model into an alarm decision via thresholding, with the threshold calibrated using risk control methods. Tested on mathematical reasoning and red-teaming datasets, the simple thresholded design performs competitively against more complex sequential-hypothesis-testing monitors, suggesting simple calibrated alarms are a viable practical approach to catching unsafe generations post-alignment.

VulDB entry for CVE-2026-90617, a remote OS command injection (CWE-78) in GH05TCREW PentestAgent. The flaw is in run_task in interface/main.py of the MCP HTTP Server, affects everything up to commit cf882dab, and has a public exploit. The product uses rolling releases, so no version ranges exist, and the fix is an unmerged pull request. The analysis suggests compensating controls: restrict network access to the MCP server, run with least privilege, and validate input upstream.

CVE-2026-91931 is a critical remote code execution vulnerability in Flowise versions before 3.1.4, triggered through the platform's Custom MCP feature which invokes npx to run Model Context Protocol servers. A fix is available in 3.1.4; the flaw scores 9.0 (Critical) on CVSS, indicating an attacker can achieve arbitrary code execution likely via unsanitized input to the npx invocation path.

who-let-the-agents-act is a self-hostable lab suite (Docker/Python, Groq-backed LLM agent) with nine isolated scenarios — overpowered data tools, IDOR-style cross-account access, unsafe agent handoffs, refund-limit bypass, indirect prompt injection via poisoned invoices, multi-tenant RAG leakage, secret leakage through debugging, fail-open approval outages, and a multi-hop confused-deputy agent chain. Each scenario runs in multiple modes (vulnerable vs. application-enforced) against the same prompt, recording model plan, policy decision, tool calls, and DB access as JSON so a reader can directly compare what changes when authorization is enforced outside the system prompt.

RedEvoAgent is a black-box automatic red-teaming agent that distills successful jailbreak trajectories into concise, human-readable 'attack skills' rather than retrieving full past trajectories. It evolves these skills via tool-effectiveness profiling and a validation ratchet that only keeps updates improving attack success, and is shown to outperform fixed and agentic jailbreak baselines while transferring across attacker models and target execution harnesses (product-level agent environments where jailbreaks trigger real tool use, not just unsafe text).

ERC-8427 'Portable Spend Grants' is a draft Ethereum standard defining a signed SpendGrant object that lets a principal authorize a delegate (e.g. an AI agent or session key) to spend up to specified per-call, trailing-24h, and lifetime caps of named assets, to a restricted set of recipients, within a validity window — solving problems that plain ERC-20 approve and midnight-resetting daily caps don't. A non-custodial registry tracks remaining usage and revocation while an immutable executor contract must call consume() in the same transaction as any transfer, so unauthorized value movement is provably blocked; the reference implementation is deployed on Arc testnet with formal verification (Halmos) of expiry, cap, revocation and executor-binding invariants plus fuzzing of the rolling-window logic. The thread also discusses interplay with ERC-7710/7715 delegation/permission RPCs, ERC-8226's regulated grants, and ERC-8312's usage-tracking pattern, and solicits feedback on EIP-7702 signer/delegation ordering and executor-vs-delegate binding in consume().

This arXiv paper derives exact conditions under which private/encrypted mempools still leak enough information (transaction pair, direction, and a coarse size range) to make sandwich attacks profitable against a fee-free constant-product AMM (the Uniswap v2 pricing rule). It shows the smallest size consistent with the leak determines the optimal front-run and its guaranteed profit in closed form, and that multi-trader first-price auctions for sandwich rights hand all expected rent to the auctioneer; it also shows hiding trade direction prevents a single non-contingent front-run from covering both directions, though post-trade arbitrage can survive even perfect pre-trade hiding. The results give privacy-layer designers a precise threshold for how much size information must stay hidden to rule out profitable sandwiching.

Bitget disclosed a $351.6M hot-wallet breach in which attackers did not compromise private keys but instead breached a core wallet backend and spoofed transaction data to trick Bitget's own authorization process into approving transfers. Attackers quickly converted most stolen EVM assets into 67,982 ETH (~$183M) and also took ~103M XRP to move into harder-to-freeze native assets, while Bitget's CEO and independent researcher Specter linked the attack to North Korea via VPN IP overlap and onchain infrastructure tied to the earlier AFX exploit attributed to TraderTraitor.

This arXiv preprint proposes a variational framework generalizing the time-dependent variational principle to simulate stochastic quantum trajectories in interacting bosonic systems, using a wavefunction ansatz of coherent superpositions of Gaussian wavepackets. The method is benchmarked on a Bose-Hubbard dimer and applied to 1D and 2D extended Bose-Hubbard lattices, revealing a symmetry-breaking phase transition present only in 2D. This is a quantum physics simulation technique, not an AI/ML method, despite using the term "variational" which overlaps with ML vocabulary.

This paper describes a hypothesis-driven simulation workflow (using the Snowglobe simulator) for screening candidate LLM-based customer experience agents before production deployment, applied to Nubank's Card Delivery and Card Management chat-support agents in Brazil at 140M-user scale. Synthetic customers and simulated tool outputs let the team test multi-step agentic workflows without hitting production backends; across 4 deployed versions, simulated evaluator scores correlated strongly with production outcomes, and simulation-guided iteration lifted transactional NPS by 36.69 points and self-service rate by 8.82 points in live A/B tests.

Socket's Threat Research team dissects a malicious Firefox extension (pdf-para-texto@extensao.local, "PDF Identity Verifier") that ships with no hardcoded malicious code — all attack logic is fetched as data into browser.storage.local after install via a lookalike domain (pdf.gusercontent.com), evading static store review. Once armed, it abuses Google's FedCM API to silently identify the victim, injects a live automation script into real accounts.google.com pages to drive an invisible account-takeover flow (bypassing password entry, forcing passkey challenges, dodging Google's bot detection, and forcing/capturing a password reset), while a webRequest listener steals the oauth_token session cookie from Set-Cookie headers — giving the attacker both a live session and a durable new password. The campaign targets Portuguese- and Spanish-speaking users starting September 2026 and includes full IOCs (domains, file hashes) and remediation steps.

Adversa AI catalogs ten distinct Claude Code attacks documented between September 2025 and September 2026: the Miasma supply-chain worm that hit 73 Microsoft repos via a SessionStart hook, TrustFall's unsandboxed MCP server execution on folder-trust, Check Point's CVE-2025-59536/CVE-2026-21852 pre-trust-dialog code execution and API key theft, Sentry-DSN-based "Agentjacking" prompt injection via fake bug reports, a 50-subcommand cap that silently disables deny rules, the SymJack symlink-to-config-hijack primitive working across six agent CLIs, Wiz's GhostApproval deceptive-approval-prompt finding (with CVE-2026-12958 at AWS and CVE-2026-50549 at Cursor but none at Anthropic), the Plugin4Shell SHA/branch-name collision bypassing plugin pinning, an academic MCP tool-poisoning paper achieving RCE on agent/LLM pairs, and SkillCloak's self-extracting-packer bypass of skill scanners. The piece argues almost none of these are model-behavior bugs - they are trust-boundary and consent failures in the surrounding tooling - and closes by pitching Adversa's own runtime agent security gateway as the fix.

Orca Security details a supply-chain attack on the npm package @dforge-core/dforge-mcp, where a compromised maintainer account modified the GitHub Actions release workflow so any push to main triggered an OIDC-based trusted publish, shipping malicious version 0.2.21 with valid Sigstore provenance. The four-stage GHAPPIER loader activated only when the MCP server launched, deployed a self-deleting remote shell, and per CloudSEK's tracing appeared across 65 repos and 22 accounts; a second payload matched PolinRider, a DPRK-linked campaign using Ethereum transactions for C2. The piece underscores that npm provenance attests build origin, not source integrity, and lists remediation steps since no CVE or advisory yet exists.

A large-scale (N=110) within-subject HCI study measuring the behavioral, oculomotor, and physiological costs of video passthrough head-mounted displays versus natural viewing during a block assembly task. The authors find a four-fold suppression of rotational head velocity and decoupled head-gaze coordination under passthrough, terming this "Passthrough Rigidity" — a shift toward motor caution and oculomotor compensation that correlates with worse task performance, increased ocular strain, and cognitive load, offering a quantitative framework for improving future XR device comfort.

A Docker-based exploitation lab for CVE-2026-26980, an unauthenticated blind SQL injection in Ghost CMS's Content API (versions before 6.19.1). The bug lives in slug-filter-order.js, where slug values from the array-notation filter syntax (filter=slug:['value']) are interpolated unsanitized into an ORDER BY CASE statement, letting NQL's single-quote-wrapped literals smuggle raw SQL past input validation; since MySQL treats || as OR and empty strings as falsy, attackers get a clean boolean oracle to extract data (e.g. admin email/password hash) from any Ghost site using only the publicly embedded Content API key. The repo includes exploit.py for full setup/verify/extract, a docker-compose lab spinning up both vulnerable (6.18.0) and patched (6.19.1) Ghost instances, and also mentions a second patched bug (jsonpath/static-eval prototype pollution in the {{#get}} Handlebars helper leading to RCE via themes).

Socket's research team found two beta releases of the @joyfill npm packages (@joyfill/layouts and @joyfill/components) contained an import-time JavaScript implant that resolves encrypted payloads through Tron, Aptos, and BNB Smart Chain transactions, ultimately dropping a 77KB Node.js remote-access trojan matching the DEV#POPPER family and sharing loader fingerprints with the PolinRider blockchain-loader campaign. The RAT establishes a Socket.IO C2 channel, executes arbitrary JS/shell commands, exfiltrates files and clipboard data, and persists by patching files inside VS Code, Cursor, Antigravity, Discord Desktop, GitHub Desktop, and the global npm CLI; a parallel detached-process branch fetches an additional bootstrap that can deploy a Python credential/browser-data stealer assessed as an OmniStealer variant. Because the implant fires on module load (not via npm lifecycle scripts), `--ignore-scripts` provides no protection, and the writeup includes full IOCs, blockchain addresses, C2 infrastructure, and MITRE ATT&CK mappings.
