Specifically, versions prior to 2026.3.31 contain a time-of-check-time-of-use (TOCTOU) race condition within the \u003ccode\u003ereadFile\u003c/code\u003e function of its remote filesystem bridge. This flaw allows malicious actors to potentially escape the intended sandbox environment. The vulnerability arises from the separation of path validation and file read operations, creating a window of opportunity for attackers to manipulate file access and circumvent security controls. Successful exploitation could lead to unauthorized access to sensitive files and data residing outside the designated sandbox. Defenders should prioritize patching to version 2026.3.31 or later to mitigate this risk.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eThe attacker gains initial access to a system running a vulnerable version of OpenClaw.\u003c/li\u003e\n\u003cli\u003eThe attacker crafts a request targeting the \u003ccode\u003ereadFile\u003c/code\u003e function in the remote filesystem bridge.\u003c/li\u003e\n\u003cli\u003eThe request includes a path to a file intended to be accessed within the sandbox.\u003c/li\u003e\n\u003cli\u003eOpenClaw performs a path validation check on the requested file path, which initially passes.\u003c/li\u003e\n\u003cli\u003eBetween the path validation check and the actual file read operation, the attacker manipulates the filesystem, potentially through a symbolic link or other means, to point the original path to a file outside the sandbox.\u003c/li\u003e\n\u003cli\u003eThe \u003ccode\u003ereadFile\u003c/code\u003e function proceeds to read the file located at the modified path, bypassing the intended sandbox restrictions.\u003c/li\u003e\n\u003cli\u003eThe contents of the arbitrary file are then exposed to the attacker.\u003c/li\u003e\n\u003cli\u003eThe attacker obtains sensitive information or achieves further escalation of privileges based on the exposed file contents.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2026-41296 can lead to a complete bypass of the OpenClaw sandbox environment.
