## Affected Packages / Versions - Package: `openclaw` (npm) - Affected versions: `< 2026.4.20` - Patched version: `2026.4.20` ## Impact Workspace `.env` loading did not reserve the `OPENCLAW_` runtime-control namespace broadly enough. A malicious workspace could set variables such as `OPENCLAW_GIT_DIR` before source-update or installer flows, potentially steering trusted OpenClaw runtime behavior. This requires running OpenClaw from an attacker-controlled workspace. Severity is medium. ## Fix OpenClaw now reserves the workspace `OPENCLAW_` environment namespace and rejects workspace dotenv entries for OpenClaw runtime-control variables. Fix commit: - `018494fa3ebb9145112e68b56fe1cb2e9f9a9ed6` ## Release Fixed in OpenClaw `2026.4.20`.
