    CVE-2026-102764 is an unauthenticated RCE in BeyondTrust Remote Support, already exploited and in CISA KEV. Rapid7 published an analysis and opened a Metasploit pull request on 30 October 2026, showing code execution on version 24.1.2 via a forged "local" message origin, the native file-transfer service and a PHP file written to the web root. BT26-05 (CVSS 4.0 9.3) is fixed by patch BT26-05-RS; SaaS was patched by 9 October.

  2. 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.

  3. ERC-8478: x402 Payee Verification for ERC-8004 Agents

    ERC-8478 is a draft Ethereum standard that binds the payTo address in an x402 payment requirement to the seller's ERC-8004 agent identity. A payer compares payTo with the registered agentWallet, or accepts an EIP-712 payee delegation signed by it, and checks that the origin is listed in the registration file. On Robinhood Chain, 5 of 5,575 x402-responding agents had payTo equal to agentWallet (28 October 2026).

    ERC-8478 is a draft Ethereum standard that binds the x402 payTo address to an ERC-8004 agent's identity, to stop payee redirection by a hijacked domain, proxy or injected tool result. A payTo must equal the agentWallet or carry an EIP-712 delegation signed by it, and the origin must be listed in the registration file. On Robinhood Chain, 5 of 5,575 x402-responding agents used their agentWallet as payTo (28 October 2026).

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.

Its tool catalog is 3,043 tokens, against a claimed 509,696 for the established reverse-engineering MCP server. Paged output with a byte budget shrinks a 541 MB Electron app to a 15 KB result, 1.3 MB of JSON to 7.9 KB, and a 450 KB build diff to 1.2 KB. radare2, rizin or Ghidra plug in for disassembly, and `npx hexvero setup --apply` registers it with Claude Code, Cursor, Codex and 15 more clients.

    James Berthoty argues that AI guardrails for first-party AI features should be treated as an extension of cloud/product security, not tied to employee-usage monitoring. Guardrails (prompt injection defense, content filtering, goal alignment) are available from AI security vendors, gateways, frontier providers and SDKs. He recommends deploying in-depth guardrails through developer SDKs or an existing cloud runtime/CADR provider, because those see what happens on the workload (such as a prompt injection leading to workload takeover, or the files a malicious MCP call wrote). Dedicated AI security vendors offer an integrated policy engine and deeper AI red-teaming, but they are usually run by internal IT rather than cloud/product security teams.

The bug allows unauthenticated arbitrary file write via crafted HTTP/HTTPS requests on FortiMail 7.2.0–7.2.9, 7.4.0–7.4.8, 7.6.0–7.6.6, and 8.0.0–8.0.1, with fixes coming in 8.0.2/7.6.7/7.4.9+ and an interim workaround of disabling IBE and restricting management-interface internet access. Federal agencies face an October 4, 2026 BOD 26-04 remediation deadline, and Fortinet's advisory (FG-IR-26-175) includes IoCs for hunting.

    An X post presenting Reversecore MCP, an MCP server that wraps authorized reverse-engineering, malware-analysis, forensics and SAST-style tools such as radare2. The user picks a profile, points it at a sample, and the agent gets structured results back in the session without driving the tools by hand. It is a concrete example of profile-based tool exposure for specialized toolchains, offered as a free alternative to a commercial IDA setup. The post stresses authorized analysis only.

    Open-Dots is an open-source reimplementation of OpenAI's "Dots" computer-use agent, giving it browser, terminal and file control plus connectors to personal apps, and designed to work with any LLM rather than being locked to one provider. The tweet thread announces the project and links to its GitHub repository.

  48. Granite0x Security Thread

    A Twitter/X thread that maps ten GitHub repos into a 'graph vs loop' framework for building trustworthy multi-agent coding systems: the graph layer covers task orchestration (bernstein's DAG scheduler), git-worktree isolation (agent-worktree), and specialist subagent roles (wshobson/agents), while the loop layer covers memory (beads), a minimal agent loop (waku-agent), token-efficient symbol-level context retrieval (serena), enforced skills/TDD (superpowers), a second-model review gate as a Stop hook (claude-review-loop), and trace-replay evals (raindrop-ai/workshop). Each repo entry includes concrete implementation details (file names, line counts, install commands) and a stated 'trap' or limitation, distinguishing substantive tools from surface-level pitches.

    A short first-person thread describing stealing credentials from a running system as an unprivileged userland process: sniffing the clipboard to grab passwords copied out of KeePass, scraping process memory and SQLite databases for stored passwords/usernames/tokens/cookies, hunting for files like password.txt, and reading Chrome/browser credentials straight out of RAM as they sit in cleartext in text boxes. The author's point is that once someone else's code is running on your machine, it's practically impossible to fully harden every surface β€” clipboard, memory, and disk are all exposed.
