Technical details
A path traversal vulnerability exists in the All-in-One WP Migration and Backup plugin due to insufficient sanitization of the 'storage' parameter. By sending a specially crafted request that exceeds the PHP 'max_input_vars' limit, an attacker can trigger a PHP warning that is captured by the plugin's shutdown handler. This handler uses the unsanitized 'storage' parameter to construct a file path, allowing the attacker to write a log file (containing JSON-formatted error data) to arbitrary directories outside the intended storage folder. The attack is unauthenticated and does not require a valid secret key, though the resulting file extension is restricted to '.log'. This issue is fixed in version 7.106.
