Description
CVE-2026-41296 is a high-severity race condition vulnerability in OpenClaw before version 2026.3.31. It involves a time-of-check to time-of-use (TOCTOU) flaw in the remote filesystem bridge's readFile function. This flaw allows attackers with limited privileges to bypass sandbox restrictions and read arbitrary files by exploiting the separate path validation and file read operations.
