Description
OpenClaw before 2026.3.31 contains a time-of-check-time-of-use race condition in the remote filesystem bridge readFile function that allows sandbox escape. Attackers can exploit the separate path validation and file read operations to bypass sandbox restrictions and read arbitrary files.
