Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
OpenHarness prior to commit 166fcfe contains an improper access control vulnerability in built-in file tools due to inconsistent parameter handling in permission enforcement, allowing attackers who can influence agent tool execution to read arbitrary local files outside the intended repository scope. Attackers can exploit the path parameter not being passed to the PermissionChecker in read_file, write_file, edit_file, and notebook_edit tools to bypass deny rules and access sensitive files such as configuration files, credentials, and SSH material, or create and overwrite files in restricted host paths in full_auto mode.

How this class of weakness works · CWE-863

An authorization check exists but is flawed, so it passes when it should fail. Attackers probe roles and object references to find the gap. Remediation means centralising and correctly implementing the access-control logic, then testing it against every role.

  1. 1. Navigate to the OpenHarness repository directory
  2. 2. Fetch the latest changes from the remote repository: git fetch origin
  3. 3. Apply the security fix by checking out or pulling the specific commit: git checkout 166fcfefb7614dbac51bd061f56542725b0298e9
  4. 4. Verify the fix was applied by reviewing the changes to file tool permission handling in the PermissionChecker implementation
  5. 5. Ensure the path parameter is now correctly passed to PermissionChecker for read_file, write_file, edit_file, and notebook_edit tools
  6. 6. Test that the permission enforcement now correctly denies access to files outside the intended repository scope
  7. 7. Rebuild and redeploy the OpenHarness instance
