Description
CVE-2026-41338 is a time-of-check to time-of-use (TOCTOU) race condition vulnerability in OpenClaw versions before 2026.3.31. It affects sandbox file operations where attackers can exploit check-then-act patterns in functions like apply_patch, remove, and mkdir to bypass file descriptor-based defenses by manipulating files between validation and execution.
