Description
The vulnerability allows a local user to modify files outside the intended validated path.
The vulnerability exists due to a time-of-check time-of-use race condition in the sandbox fs-bridge staged write flow when creating and populating temporary files before commit. A local user can race a parent-path alias change to cause writes outside the intended validated path.
The issue affects the temporary file materialization step before the final guarded replace operation, resulting in a sandbox boundary bypass within the writable mount scope.
