      <title>BREW-openclaw-cli-GHSA-x82f-27x3-q89c — OpenClaw's TOCTOU symlink race in writeFileWithinRoot could create or truncate files outside root boundaries</title>
      <link>https://vulnerability.circl.lu/vuln/brew-openclaw-cli-ghsa-x82f-27x3-q89c</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Homebrew: openclaw-cli&lt;/p&gt;
&lt;p&gt;### Summary
A symlink-retarget TOCTOU race in `writeFileWithinRoot` could point an attacker-controlled path alias outside the configured root between resolution and write operations.&lt;/p&gt;
&lt;p&gt;### Impact
Affected versions could cause out-of-root write side effects (including file creation or truncation) before final boundary validation.&lt;/p&gt;
&lt;p&gt;### 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.&lt;/p&gt;
&lt;p&gt;### Affected and Patched Versions
- Affected: `&amp;lt;= 2026.2.26`
- Patched: `2026.3.1`&lt;/p&gt;</description>
