CVE
GHSA-x82f-27x3-q89c
OpenClaw's TOCTOU symlink race in writeFileWithinRoot could create or truncate files outside root boundaries
Summary
A symlink-retarget TOCTOU race in writeFileWithinRoot could point an attacker-controlled path alias outside the configured root between resolution and write operations.
Impact
Affected versions could cause out-of-root write side effects (including file creation or truncation) before final boundary validation.
Fix
Root-scoped write flow now opens existing files without pre-truncation, creates missing files with exclusive create semantics, truncates only after post-open identity/boundary checks, and removes out-of-root artifacts when a race is detected.
