Spectra – WordPress Gutenberg Blocks <= 2.12.6 - Authenticated (Contributor+) Path Traversal

The Spectra – WordPress Gutenberg Blocks plugin for WordPress is vulnerable to Path Traversal in versions up to, and including, 2.12.6 via the get_block_default_attributes function. This allows authenticated attackers, with contributor-level permissions and above, to read the contents of any files named attributes.php on the server, which can contain sensitive information.
