CVE-2026-43584

OpenClaw: Exec environment denylist missed high-risk interpreter startup variables

Summary

Exec environment denylist missed high-risk interpreter startup variables.

Affected Packages / Versions

  • Package: openclaw
  • Ecosystem: npm
  • Affected versions: < 2026.4.10
  • Patched versions: >= 2026.4.10

Impact

The exec environment policy missed interpreter startup variables such as VIMINIT, EXINIT, LUA_INIT, and HOSTALIASES, allowing operator-supplied environment overrides to influence downstream execution or network behavior.

Technical Details

The fix expands the host environment security policy denylist to cover these and related high-risk environment variables, with regression coverage.

Fix

The issue was fixed in #63277. The first stable tag containing the fix is v2026.4.10, and openclaw@2026.4.14 includes the fix.
