Specifically, the application loads a \u003ccode\u003e.env\u003c/code\u003e file from the current working directory before applying configurations from trusted state directories. This design flaw allows a malicious actor to inject arbitrary environment variables by placing a crafted \u003ccode\u003e.env\u003c/code\u003e file within a repository or workspace where OpenClaw is executed. Successful exploitation leads to the overriding of runtime configurations, including potentially security-sensitive environment settings, upon OpenClaw's startup. This vulnerability poses a significant risk to the application's integrity and security posture.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAttacker identifies an OpenClaw deployment or development environment.\u003c/li\u003e\n\u003cli\u003eAttacker crafts a malicious \u003ccode\u003e.env\u003c/code\u003e file containing environment variables designed to compromise OpenClaw's configuration.\u003c/li\u003e\n\u003cli\u003eThe attacker places the malicious \u003ccode\u003e.env\u003c/code\u003e file in the current working directory of the OpenClaw application.
