The spacecookie library versions from 0.2.0.0 up to but not including 1.0.0.3 contain a vulnerability in the path sanitization functions `sanitizePath` and `sanitizeIfNotUrl`. These functions fail to properly remove `..` components from paths due to erroneous comparison logic, which could allow path traversal attacks. The issue is fixed in version 1.0.0.3 by using a correct comparison method. The spacecookie server executable included in the package is not affected due to an additional separate check.
