CVE-2026-41294

Configuration takeover via untrusted workspace dotenv

Published Apr 20, 2026 · Updated Apr 20, 2026

Environment variable injection in OpenClaw before 2026.3.28 allows context-dependent attackers to override runtime settings via a workspace .env file. The loaders in src/infra/dotenv.ts and src/cli/dotenv.ts read the current working directory file before trusted state-directory configuration and accept its security-sensitive entries. Exploitation requires a crafted repository or workspace and user interaction to start OpenClaw from that directory, after which injected values control configuration available to the process.
