GHSA-x82f-27x3-q89c · OpenClaw's TOCTOU symlink race in writeFileWithinRoot could create or truncate files outside root boundaries
This page contains facts from public vulnerability sources. Check the original advisory before updating.
### 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. ### Affected and Patched Versions - Affected: `<= 2026.2.26` - Patched: `2026.3.1`
