The helper calls `parse_url($filename, PHP_URL_SCHEME)` and then checks `is_string($scheme) && strlen($scheme) > 1` to reject stream wrappers such as `phar://`, `php://`, `data://` or `expect://`. The check is not equivalent to \"does the path contain a wrapper\". When the input has the form `phar:///path/file.phar/inner` with three or more slashes after the scheme, `parse_url` returns boolean `false` instead of returning the scheme string. The `is_string($scheme)` branch is therefore skipped, the helper returns without throwing, and the caller proceeds. PHP's stream layer, however, still treats `phar:///...` as a valid phar wrapper and opens the underlying phar file. The result is that `IOFactory::load($attackerPath)` walks past the patch and still touches the phar wrapper. On PHP 7.x, simply reaching the phar wrapper via `is_file` is enough for PHP to automatically deserialize the phar metadata, which in turn invokes the magic methods `__wakeup` and `__destruct` of an attacker controlled object and gives full RCE. On PHP 8.x, automatic metadata deserialization for plain file ops was removed, so the chain","public_affected_ranges":["ECOSYSTEM: introduced 0; fixed 1.30.5"]}],"null_published_at":"2026-11-02T20:21:07.851Z","source_updated_at":"2026-09-10T03:50:48.782Z","source_disclosed_at":"2026-06-08T23:00:14.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"Source facts changed; compare the preserved prior revision.","null_first_observed_at":"2026-10-31T21:41:59.958Z"},{"id":"NVI-00004605","kind":"vulnerability","title":"PHPSpreadsheet has a patch bypass for CVE-2026-34084 ","revision":2,"unknowns":["Customer inventory, deployment, reachability and exploitation have not been inspected."],"lifecycle":"active","identifiers":["GHSA-87m4-826x-3crx","CVE-2026-45034"],"plain_summary":"OSV carries this publisher advisory for phpoffice/phpspreadsheet.
