Shubham Mishra π (@shubh6200) on XA post relaying Cursor's security advisory: a modified, malicious Claude Code VS Code extension was distributed through the Cursor extension marketplace, affecting at most 5,000 users. Anthropic did not develop that version, and other extensions are not affected. Users of Claude Code in Cursor are told to update to version 2.1.314. The post adds that marketplaces need publisher verification and package integrity checks. It gives no technical detail on the payload.

It is exploitable only while a machine is PXE network booting and the attacker sends an oversized ICMP error from the same network. Code execution also needs the exact firmware build, and Secure Boot does not help. The fix landed in EDK II main on 15 October but is not in a stable release. No known exploitation, and not in CISA KEV.

A web page silently writes a fake AGENTS.md or CLAUDE.md into a Downloads folder, and Codex and Claude Code follow it as project rules. Codex then wrote an attacker's MCP server into the machine-wide config, so one injection becomes a standing connection for every session. It asks whether teams inventory runtime MCP connections against approved lists.

On Windows and WSL, a remote MCP server could run code during OAuth sign-in, because the server-chosen authorization URL was put unescaped into a PowerShell command, so a PowerShell subexpression executed. opencode fixed it in 1.18.33 on Sep 28 as a browser-launch refactor with no advisory or CVE. MCP Inspector published an advisory for the same bug class, and its fix needs a major bump of the open package.

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.
