The vulnerability stems from the setXML method in Auth/Yadis/XML.php, which processed untrusted XML input without proper XXE protections. The GitHub patch explicitly adds libxml_disable_entity_loader(true) and error handling around the loadXML call, confirming this was the vulnerable code path. The TYPO3/CMS package is listed as vulnerable due to its dependency on php-openid, but the root vulnerable function resides in the openid library's XML parser implementation.
