Description

## Summary `PIP_INDEX_URL` and `UV_INDEX_URL` bypass host exec env sanitization and redirect Python package-index traffic ## Current Maintainer Triage - Status: narrow - Normalized severity: high - Assessment: v2026.3.28 still allows Python package-index env redirection through host exec, but scope should stay limited to approved or allowlisted package-management exec paths, not arbitrary remote execution. ## Affected Packages / Versions - Package: `openclaw` (npm) - Latest published npm version: `2026.3.31` - Vulnerable version range: `<=2026.3.28` - Patched versions: `>= 2026.3.31` - First stable tag containing the fix: `v2026.3.31` ## Fix Commit(s) - `7ae1bb0c7799fd0cbd2d4de7b0f5b8039837ab8d` — 2026-03-31T09:53:32+09:00 OpenClaw thanks @nexrin for reporting.
