[critical] OpenCode: malicious MCP server can run code on Windows/WSL during sign-in (no CVE)

Thu, 22 Oct 2026 14:00:44 GMT

A command-injection flaw in the OpenCode AI coding agent let a malicious or later-hijacked remote MCP server run PowerShell commands on a developer's Windows or WSL machine when they started the MCP OAuth sign-in. The server-supplied authorization endpoint was passed unescaped to an old version of the open package. Anomaly fixed it in 1.18.33 on Sep 28 without a CVE or advisory, so scanners won't flag 1.0.137 through 1.18.32. macOS and Linux are not affected. Pillar Security found it and rates it 9.8; no in-the-wild exploitation reported.

Status: live · Patch: patched · Fixed in: OpenCode 1.18.33

Latest updates:

2026-10-22: The Hacker News reports the flaw; upgrade to 1.18.33, run `opencode mcp list`, and remove unvetted remote MCP servers. (source)
2026-10-19: Pillar Security discloses the flaw publicly. Anomaly declined to request a CVE, saying user-configured MCP servers are outside its trust boundary. (source)
2026-09-28: OpenCode 1.18.33 ships the fix as a routine browser-launch refactor; release notes don't mention security. (source)
