…tifier() The method replaced '/' with DIRECTORY_SEPARATOR but never canonicalized the resulting path, so IDs containing '..' sequences could escape the configured cache location directory. Fix: after building the identifier string, resolve the target directory with realpath() and verify it starts with the cache base directory. ezcBaseValueException is thrown if the resolved path escapes the base.
