Pre-ERC: Agent Pre-Sign Risk Report

Pre-ERC: Agent Pre-Sign Risk Report is a draft Ethereum Magicians proposal for an EIP-712-signed report that a risk source, identified by an ERC-8004 identity, returns about one unsigned request. It carries typed findings on tokens, approvals, addresses, payments (x402) and texts, and each finding is marked read or not read. It has no score or verdict, so the consumer applies its own policy. The author's live implementation, toll, runs on Robinhood Chain.

ERC draft: Independent Simulation Result for (STVA)

ERC draft "Independent Simulation Result" (STVA) defines a canonical, content-addressed SimulationResult (success, gasUsed, returnData, stateDiffHash, logsHash, snapshotId, resultHash) that any wallet, hardware device or verifier can recompute from the same VerificationPayload and state snapshot. It targets compromised-frontend and UI/calldata-mismatch attacks, and defines Basic, Standard and Strict compliance levels. Open questions are stateDiff encoding, prestate proofs and binding to capability tokens.

DBHub, a database MCP server, had a read-only mode bypass in its SQL check. The check treated every `--` as a comment, but MySQL only starts a comment when whitespace follows it. A hidden write statement could therefore still run, and a prompt injection could trigger it. Fixed in version 0.22.6. Replies say enforcement belongs in database grants and that parser tests need to be dialect-specific.

Pre-ERC: x402 Payee Verification for ERC-8004 Agents

Pre-ERC draft on Ethereum Magicians that binds the x402 payTo address to an ERC-8004 agent's registered agentWallet, directly or through an EIP-712 payee delegation (ERC-1271 for contract wallets). It lists eight fixed checker outcomes and requires the resource origin to appear in the registration file. On Robinhood Chain (28 October 2026), 5,575 of 20,046 agents answered with x402 requirements, and only 5 used their agentWallet as payTo.

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.

Tollbooth DPYC's "Secure Courier" is a consent scheme that lets an AI agent act for a Nostr npub at a paid MCP service without holding the user's nsec. The service sends a signed, sealed Nostr direct message, the user replies signed with their nsec and sets an expiry, and the service issues its own grant. The thread contrasts this with central identity providers and CIBA, arguing a breach reaches only grants that service issued.

Reply on X explaining a Bytecode Alliance advisory for Wasmtime's Cranelift compiler backend. A large or crafted Wasm function that generates enough SSA values overflows Cranelift's value-index representation, which packed indices into 24-bit fields. The fix widens them to 32 bits. The issue is not AArch64-specific, and the advisory names no required optimisation level. Guard pages do not reliably stop the resulting miscompilation and type confusion, so a sandbox escape can arise at compile time.

leanrea is an 8 KB skill file that tells a coding agent which plain CLI tools to use for reverse engineering, replacing the 207-tool REA MCP server. The author's test reports 38% faster, 35% cheaper, and a score of 74/75 against REA's 75/75. Caveats listed: 3 runs per task, one model, one machine, and Claude with no skill already performed decently. Replies question whether the lost point was a task where structured tool output beat parsing CLI text.

Previdian Cyber reports an exploitation attempt against its FortiSIEM honeypot on 23 October 2026 at 09:43:32 UTC, targeting the FortiSIEM path traversal CVE-2026-106173. The request, from 85.192.29[.]68, POSTed to /phoenix.phoenixSvc/SendQueryResult on TCP 27918 with twelve ../ sequences in the query-id header, trying to overwrite /tmp/.fsmprobe with an empty file. It matches the file overwrite mode of the Horizon3.ai PoC; success is not confirmed. Mitigation: upgrade to FortiSIEM 7.5.1 or later and restrict TCP 27918.

MalwareTech thread arguing that many public "php2shell" exploits for CVE-2026-109618/CVE-2026-109619 are LLM hallucinations. The code shown is PHP session poisoning used to exploit local file inclusion in PHP apps, not a PHP vulnerability. It shares only the PHP_SESSION_UPLOAD_PROGRESS feature with the CVEs. Honeypot traffic shows non-working attempts, and AI-assisted triage wrongly confirmed mass exploitation. The real bug works only on a few PHP versions with specific configurations. Mitigation is setting session.upload_progress.enabled to Off.

The skill works across models and agent harnesses, including free models, and outputs machine-readable reports. It calls for sandboxing, proof of real impact and independent checks. The thread also covers GitLab CVE-2026-110264 (CVSS 10.0, unauthenticated RCE), two AI-found PHP RCE flaws, and a Railway secret-theft warning.

ns2jb is a software-only jailbreak for the Nintendo Switch 2 running firmware 23.0.1, announced in a post on X. It runs arbitrary native code, allows save dumping, reverse engineering and game modding, and reaches most peripherals via MMIO. It is tethered (rerun after reboot) and gives no CFW or full kernel control. The post says Mario Kart World has been modded with custom characters. It gives no technical detail on the exploit chain.

LiteLLM suspects its October 21 release compromise began with Claude Code responses containing GitHub CLI OAuth tokens that were written to logs of an internet-facing internal LiteLLM gateway. Attackers allegedly stole those tokens, used an organization-owner token to disable branch protections, and pushed poisoned artifacts from a lookalike repository. How they entered the gateway is unconfirmed, and this is not a proven Claude Code vulnerability.

Post on the LiteLLM 1.107.0 PyPI compromise published 21 October 2026 and quarantined about 1 hour 43 minutes later. A malicious .pth file ran at Python startup and stole cloud credentials, private keys, browser data and AI tool auth files, then POSTed a tarball to an attacker endpoint. The author says attackers used stolen GitHub CLI OAuth tokens to push a trojanized commit chain and build official wheels. It lists five defenses: hash-pinned lockfiles, per-tool capped keys, release cooling periods, secret isolation and egress monitoring.

The flaw is a CVSS 10.0 unauthenticated RCE on self-managed GitLab servers, affecting 12 years of releases, found by joaxcar.

Post describing a LiteLLM 1.107.0 PyPI compromise in which attackers used stolen GitHub CLI OAuth tokens from three engineers to trigger and approve the project-releaser workflow, producing eight malicious wheels and a tampered tarball. The wheels drop cook.pth, which runs at Python startup, and privcollect steals cloud tokens, keys, browser data, AI configs and LiteLLM proxy credentials, exfiltrating to litellm[.]dev/healthcheck. A second daemon polls a GitHub domain.txt hourly for new domains to fetch and execute. PyPI yanked the package the same day. The post is a single unsourced tweet.

Post summarising Pillar Security's finding of a remote code execution flaw in OpenCode, the open-source AI coding agent. Versions 1.0.137 through 1.18.32 could run code from a remote MCP server during OAuth sign-in on Windows and WSL, with no prompt injection needed. The fix is in 1.18.33 (released 28 September). No advisory or CVE was issued, so scanners will not flag old installs. Interim advice is to remove unvetted remote MCP servers.

Swif (@swif_ai) reports that in the MCP TypeScript server SDK versions 2.0 to 2.2, a single server instance shared by several HTTP clients, which is the pattern the README shows, could send one client's responses to another client. Version 2.3.0 refuses this setup, so developers must build a server per request or per session. The post gives no CVE, advisory ID or technical detail.

LiteLLM 1.107.0 on PyPI shipped malware in all 7 wheels, the package's second supply-chain attack this year. It steals SSH keys, cloud credentials, browser passwords, AI tool configs and API keys, and installs a backdoor that polls for commands hourly. The GitHub source is clean, so a hijacked build or publish step is suspected. PyPI quarantined the release, but Aikido says the Docker image litellm/litellm:1.107.0 was still live. Indicators are cook.pth, cook.py and sitecustomize.py in site-packages. The advice is to rotate reachable keys and pin 1.106.2.

Google used zero-knowledge proofs to keep the attack details secret, and the post says the secrecy lasted 63 days. The fetched text is cut off after the qubit estimate of roughly 1,200, so later details are missing.
